Abstract

An accurate thrust control of permanent magnet linear synchronous motors (PMLSM) is more efficient with a fine knowledge of the harmonics value of the electromotive force (EMF). This is often difficult to obtain experimentally for a PMLSM. As a consequence, this paper deals with the study of the non-sinusoidal EMF of a PMLSM using the 3D Finite-Element Method (FEM). Two potential formulations are used to consider several cases. Afterwards, for the same accuracy, the computation times are examined. The results of the FEM are compared to those given by the measurements from a test bench composed of a Siemens LIMES400/120 linear motor and a dSPACE DS1005 real-time controller board. Finally, the advantages and the limitations of the FE Analysis will be discussed.

Abstract

This paper presents how to compensate for the non-sinusoidal electromotive force (EMF) of the permanent magnet linear synchronous motor (PMLSM) with a multiple-frequency resonant controller. After the modeling of the non-sinusoidal EMF in a PMLSM, the multiple-frequency resonant controller is proposed to control the PMLSM in order to compensate for the negative influence of such EMF. After explaining the discrete resonant controller theory, the effectiveness of the suggested method is verified on a test bench equipped with a Rexroth LSP120C linear motor and a dSPACE DS1005 real-time controller board.

Abstract

International audience; This paper presents an original methodology for machine design. The methodology is based on nonlinear reluctance network modeling and multilevel surrogate based optimization. The reluctance network is solved by computing the meshes magnetic flux and its topology is updated for each rotor position. In order to achieve an optimal design, in terms of satisfying some specifications, a surrogate based optimization inspired from the Space Mapping (SM) technique is considered. Optimization is held on the linear model and is iteratively corrected, through a new embedded strategy, by the nonlinear one. Finally, the proposed application is a constrained minimization of axial flux machine losses on an artemis cycles.

Abstract

Linear Motors have become leading component in the field of the high-speed machine tools. Nowadays, the Permanent Magnet Linear Synchronous Motor (PMLSM) is the main component permitting to obtain higher performances than its rotary counterpart. However, to use these components in an optimal manner, it is necessary to take into account the specificities of these linear motors. Indeed, electric and magnetic phenomena, such as the non-sinusoidal electromotive forces, saturated inductances and detent forces, generate in the linear motor, the ripple forces that are disturbing for the mechanical part. Indeed, the goal of this study is to improve, in a first part, the modelling of these linear motors. Analytical methods and the finite-element method are used to show the impact of these phenomena on the electromagnetic force. Then, in a second part, we define the optimal control structures by taking into account the previously obtained models. The formalism of the Causal Ordering Graph (COG), developed at the L2EP laboratory, help to represent and to define in a systematic way the control design. Thus, the inversion principles of the COG are detailed to design the structure of feedback control and of non-feedback control. The industrial control structure is analyzed and new control structures are proposed in order to optimize the thrust of a LMD10-050 linear motor of ETEL company.; Les moteurs linéaires sont devenus des composants incontournables dans le domaine de la conception des machines de production. L'actionneur synchrone à aimants permanents (PMLSM) constitue le principal composant et permet aujourd'hui d'obtenir des performances nettement supérieures à celles de son homologue rotatif accouplé à un système de transformation de mouvement. Cependant, pour utiliser ces constituants de façon optimale, il est nécessaire de prendre en compte dans la commande les spécificités de ce type d'actionneur. En effet, des phénomènes électriques et magnétiques, tels que les forces électromotrices non-sinusoïdales, la saturation des inductances et les forces de détente, génèrent des forces ondulantes perturbatrices pour la partie mécanique. L'objectif de cette étude est donc, dans un premier temps, d'améliorer la modélisation de ces moteurs linéaires en vue de leur commande. Des méthodes analytiques et éléments-finis sont utilisées pour quantifier l'importance de ces phénomènes sur la force de poussée. Puis, dans une deuxième partie, nous définissons les structures de commande optimales permettant de prendre en compte les phénomènes retenus. Le formalisme du Graphe Informationnel Causal (GIC), développé par le laboratoire L2EP, est utilisé pour représenter et définir de façon systématique les structures de commande retenues. Les méthodologies d'inversion du GIC sont détaillées pour permettre la définition des structures de commande en Boucles Fermées et Non-Fermées. Les structures classiques de commande industrielles sont analysées et de nouvelles structures de commande sont proposées pour la commande en force d'un moteur linéaire LMD10-050 de la société ETEL.

29. Optimization based on parameter moments estimation for robust design.

Author

Picheral, Laura, Hadj-Hamou, Khaled, Remy, Ghislain, and Bigeon, Jean

Abstract

This paper deals with robust design based on analytical models. We consider that variability on design parameters are represented by the parameter Mean and Standard Deviation. We propose in this article a new robust design approach that allows the designer either to find a robust solution in a reasonable execution time or to be informed of the non-existence of a robust solution for his design problem. The process combines a reformulation of the model to integrate parameter uncertainties and a deterministic optimization algorithm with new specifications based on robust objectives. The engineering application of an electrical actuator design is presented and used to show the implementation and the effectiveness of this new robust approach. [ABSTRACT FROM PUBLISHER]

Abstract

Purpose – The purpose of this paper is to set a relation through adaptive multi-level optimization between two physical models with different accuracies; a fast coarse model and a fine time consuming model. The use case is the optimization of a permanent magnet axial flux electrical machine. Design/methodology/approach – The paper opted to set the relation between the two models through radial basis function (RBF). The optimization is held on the coarse model. The deduced solutions are used to evaluate the fine model. Thus, through an iterative process a residue RBF between models responses is built to endorse an adaptive correction. Findings – The paper shows how the use of a residue function permits, to diminish optimization time, to reduce the misalignment between the two models in a structured strategy and to find optimum solution of the fine model based on the optimization of the coarse one. The paper also provides comparison between the proposed methodology and the traditional approach (output space mapping (OSM)) and shows that in case of large misalignment between models the OSM fails. Originality/value – This paper proposes an original methodology in electromechanical design based on building a surrogate model by means of RBF on the bulk of existing physical model.
