Abstract

International audience; In this article, parallel interconnection of dc/dc converters is considered. For this topology of converters feeding a common load, it has been recently shown that dynamics related to voltage regulation can be completely separated from the current distribution without considering frequency separation arguments, which inevitably limits achievable performance. Within the Hamiltonian framework, this article shows that this separation between current distribution and voltage regulation is linked to the energy conservative quantities: the Casimir functions. Furthermore, a robust control law is given in this framework to get around the fact that the load might be unknown. In this article, we also ensure that the system converges to the optimal current repartition, without requiring explicit expression of the optimal locus. Finally, resulting control law efficiency is assessed through experimental results.

Abstract

International audience; In this paper, we consider the problem of L 2exponential stabilization of a coupled ODE-hyperbolic PDE-ODE system, where actuation is available through one ODE. Based on the backstepping technique, the system is mapped into an equivalent delay form which allows for the construction of a strictly proper controller realized as a full-state feedback. The result extends previous control designs, lifting some restrictions on the structure of the ODEs under consideration and guaranteeing a non-zero delay margin for the closed-loop system.

Abstract

SUMMARYThis paper introduces a dual-user training system whose design is based on an energetic approach. This kind of system is useful for supervised hands-on training where a trainer interacts with a trainee through two haptic devices, in order to practice on a manual task performed on a virtual or teleoperated robot (e.g., for an Minimally Invasive Surgery (MIS) task in a surgical context). This paper details the proof of stability of an Energy Shared Control (ESC) architecture we previously introduced for one degree of freedom (d.o.f.) devices. An extension to multiple degrees of freedom is proposed, along with an enhanced version of the Adaptive Authority Adjustment function. Experiments are carried out with 3 d.o.f. haptic devices in free motion as well as in contact contexts in order to show the relevance of this architecture.

Abstract

International audience; This work deals with a class of delayed port-Hamiltonian systems with control law given as a bounded output feedback. A sufficient stability condition of the resulting closed-loop dynamics is obtained combining Wirtinger-based integral inequality and Lyapunov-Krasovkii theorem. This condition is formulated in terms of (parametrized) linear matrix inequality. A numerical example shows reduction of the conservatism regarding literature result.

Abstract

International audience; This paper presents a bond graph (BG) model and a physical structural analysis of an intermediary cooling system of a power plant. The main goal is to extend the techniques already in use for the physical structural analysis of mechatronic systems to perform static analysis and diagnosis on physical models in order to state whether they are well-posed and suitable for each step of the system's lifecycle (from its design to its operation). If a problem for modeling, for simulating or for solving the given engineering question is detected, the analysis shall localize the problem in the model and give the physical interpretation of the error. The objective is not to be able to diagnose all possible physical errors, but to add another type of analysis in order to improve error detection before compiling and running a model.

Abstract

International audience; We consider the problem of full-state feedback exponential stabilization of the zero equilibrium of a (possibly unstable) coupled 2 × 2 system of linear first-order hyperbolic partial differential equations (PDEs). Unlike previous works, boundary couplings to linear ordinary differential equations (ODEs) at both boundaries are considered (under some condi- tions) and actuation is only available through one of these ODE dynamics. This structure can arise when considering linear (or linearized) systems of balance laws with finite-dimensional actuator and load dynamics. The feedback law proposed in this paper is constructed using an invertible transform based on the (infinite-dimensional) backstepping method and a suitable target system that together guarantee the exponential stability of the origin of the closed-loop system in an adequate norm.

Abstract

International audience; In this paper a passive integrator dedicated to input/output Hamiltonian systems approximation is presented. In a first step, a discrete Hamiltonian framework endowed with a Lie derivative-like formula is introduced. It is shown that the discrete dynamics encodes energy conservation and passivity. Addition- ally, the characterization of the discrete dynamics in terms of Dirac structure is shown to be invariant by interconnection. The class is thus composable: networked systems belong to the class. In a second step, the discrete dynamics is considered as a one-step integration method. The method is shown to be convergent and provides a discrete-time approximation of an input/output Hamiltonian system. Accordingly, the discrete dynamics inherits intrinsic energetic characteristics (storage function and dissipation rate) from the original system. The method is thus tagged as passive integrator. As an illustration, the closed-loop behavior of interconnected subsystems and the stabilization of a rigid body spinning around its center of mass are presented.

Abstract

International audience; This paper introduces a new controller for dual-user training systems, designed by way of an energy based approach. Dual-user training systems are useful for supervised hands-on training when a trainer shows the right gestures to a trainee and where the forces to apply on the tools are difficultto dose. An energy shared control (ESC) based architecture is proposed, based on an intrinsically passive authority sharing mechanism which is enhanced to provide a full force feedback to both users. As this enhancement may violate the natural passivity of the system, a passivity controller is introduced. A task based comparative study with two other dual-user schemes (Complementary Linear Combination (CLC) and Masters Correspondence with Environment Transfer (MECT) from [1] is conducted, which reveals analogous performances. Real-time experiments demonstrate good tracking performances.

Abstract

International audience; This paper deals with the stability of discrete closed-loop dynamics arising from digital IDA-PBC controller design. This work concerns the class of Newtonian mechanical port-Hamiltonian systems (PHSs), that is those having separable energy being quadrating in momentum (with constant mass matrix). We first introduce a discretization scheme which ensures a passivity equation relatively to the same storage and dissipation functions as the continuous-time PHS. A discrete controller is then obtained following the IDA-PBC design procedure applied to the discrete PHS system. This method guarantees that, from an energetic viewpoint, the discrete closed-loop behavior is similar to the continuous one. Under zero-state observability assumption, closed-loop stability then follows from LaSalle principle. The method is illustrated on an inertia wheel pendulum model.

The authority is detemined online according to the trainee’s behavior performance. An evaluation method is introduced based on an adaptive virtual boundary, which results into a time-varing dominance factor. An overruling function is set upstream to solve some specific cases. The system is modeled and controled in port-Hamiltonian form for passivity preserving. Experiments are conducted for validation.

Abstract

International audience; This paper addresses robust stability issues of interconnected port-Hamiltonian systems with polytopic uncertainty and time-varying delay. On the basis of a Lyapunov-Krasovskii functional and the Wirtinger's inequality (known to be less conservative than the popular Jensen's inequality) we show the improvements of the newly proposed criterion with respect to other existing ones. The stability analysis is derived based on a delay independent criterion. A classical nonlinear example taken from the literature illustrates the relevance of the results.

Abstract

International audience; We address the discrete-time passivity-based control laws synthesis within port-Hamiltonian framework. We focus on IDA-PBC design for canonical port-Hamiltonian systems with separable energy being quadratic in momentum. For this class of systems, we define a discrete Hamiltonian dynamics that exactly satisfies a discrete energy balance. We then derive a discrete controller following the IDA-PBC procedure. The proposed methodology relies on an energy discretization scheme with suitable discrete conjugate port variables. The main result is illustrated on two examples: a nonlinear pendulum in order to compare with some simulation results of the literature, and the impact oscillator which requires robust discretization scheme.

Abstract

International audience; In the context of mechatronic systems design, this paper addresses a parameter tolerance synthesis with respect to specifications including output epistemic uncertainties. The methodology proposed here concerns uncertainties modelled with fuzzy logic. The procedure relies on output uncertainties propagation through an inverse model. Design parameter tolerance is then synthesized. The results are validated injecting designed parameters in the direct model. The methodology is illustrated on a linear model with specifications including combined uncertainties.

Abstract

International audience; The goal of this article is to present an extension of the port-based modelling approach (bond graphs) which applies to systems subject to heat and mass transfer. The methodology is based on the first principle, conservation laws and constitutive closure relations. The latter are the phenomenological laws relating fluxes and thermodynamic forces. Then instantaneous power conservation appears naturally as a geometric interconnection structure called Dirac structure. The multi-level case (several macroscopic spatial scales) is investigated with the assumption that the spatial scales are separated and may be considered as two distinct phases. In this case, it is shown that both the interconnection coupling within a phase and the multi-level interconnection coupling are Dirac structures.

Abstract

For numerical simulation and control design purposes, a mixed-finite element method preserving the port Hamiltonian structure of the system has been developed. This method was successfully applied for 1D systems. In this paper, we shall suggest some generalization of this result to higher dimensional spatial domain (3D) using Whitney forms as Galerkin base. The discretization procedure is illustrated on Maxwell’s equations.

Abstract

An energy balance equation with respect to a control contact system provides port outputs which are conjugated to inputs. These conjugate variables are used to define the composition of port contact systems in the framework of contact geometry. We then propose a power-conserving interconnection structure, which generalizes the interconnection by Dirac structures in the Hamiltonian formalism. Furthermore, the composed system is again a port contact system, as illustrated on the example of a gas-piston system undergoing some irreversible transformation.

Abstract

In the context of mechatronic systems design, this thesis addresses the problem of parametric tolerance synthesis with respect to specifications including allowable uncertainties. We consider two types of uncertainty: aleatory uncertainty and epistemic uncertainty. The methodology is based on the inversion of the bond graph model and the propagation of uncertainty from output to design parameter. Aleatory uncertainties are modeled by the density probability functions (PDF). Epistemic uncertainties are modeled by membership functions (MF). The probabilistic and fuzzy bond graph are then defined. By affecting bicausality and exploiting the bicausal bond graph model, we obtain the inverse model of the system. The PDF and MF are then propagated through the inverse model to the design parameters. We propose two approaches for the propagation of uncertainty: the global approach and the local approach. In the global approach, the output PDF and MF are propagated through the overall relation between the outputs and the design parameters (the inverse model). In the local approach, the model is divided into several sub-models and the PDF and MF are transferred from sub-model to sub-model until they reach the design parameters. We then use the obtained PDF and MF for synthesizing the tolerances of the design parameters. The proposed methodology allows the treatment of aleatory uncertainty and epistemic uncertainty by appropriate tools, in a problem of parametric tolerance synthesis including complex specifications., Dans le contexte de conception des systèmes mécatroniques, cette thèse aborde le problème de synthèse de tolérance paramétrique par rapport aux spécifications incluant incertitudes admissible. Nous prenons en compte deux types d’incertitude : incertitude aléatoire et incertitude épistémique. La méthodologie est basée sur l’inversion du modèle bond graph et sur la propagation de l’incertitude en sortie au paramètre de conception. Les incertitudes aléatoires sont modélisées par les fonctions densité de probabilité (FDP). Les incertitudes épistémiques sont modélisées par les fonctions d’appartenance (FA). Les modèles bond graph probabiliste et bond graph flou correspondants sont alors définis. En affectant la bicausalité et exploitant le modèle bond graph bicausal, nous obtenons le modèle inverse du système. Les FDP et FA sont ensuite propagées à travers ce modèle inverse jusqu’aux paramètres de conception. Nous proposons deux approches pour la propagation de l’incertitude : l’approche globale et l’approche locale. Dans l’approche globale, les FDP et FA en sortie sont propagée grâce à la relation globale entre les sorties et les paramètres de conception (le modèle inverse). Dans l’approche locale, le modèle considéré est divisé en plusieurs sous-modèles et les FDP et FA sont transférées de sous-modèle en sous-modèle jusqu’aux paramètres de conception. Nous utilisons ensuite les FDP et FA obtenues pour synthétiser les tolérances pour les paramètres de conception. La méthodologie proposée permet le traitement de l’incertitude aléatoire et l’incertitude épistémique par des outils appropriés, dans un problème de synthèse de tolérance paramétrique incluant des spécifications complexes.
