1. Computer Animation Education Online: A Tool to Teach Control Systems Engineering throughout the COVID-19 Pandemic

Author

Patete, Anna and Marquez, Ronald

Abstract

The world is changing, and university education must be able to adapt to it. New technologies such as artificial intelligence and robotics are requiring tools such as simulation and process control to develop products and services. Thus, control systems engineering schools are adapting to new educational frameworks tailored to deploy promising and feasible new technologies. Herein, we have relied on computer animation-based education and its implementation as an online project-based strategy to attain the objectives and goals of the control systems engineering courses at University of Los Andes, Venezuela. The ControlAnimation library developed in Mathematica program in 2002 has been used as a tool to teach control systems engineering courses since 2008 and with greater prominence since 2020, when the stay-at-home orders due to the COVID-19 pandemic were enacted. Consequently, computer animation-based education has proven its feasibility as an online tool combined with project-based learning techniques, thus allowing students to interact with an animated control system by changing the mathematical model and the design parameters of control laws in a comfortable and somewhat playful way. This enabled new capabilities to study the dynamic behaviors of primordial control systems online. In addition, it allowed students to co-identify and relate in a more intuitive way to the mathematical models and control equations with the physical behavior of the real control systems.

Abstract

Los problemas más importantes de los controladores auto-ajustables, se refieren a la estabilidad, desempeño y convergencia de los algoritmos recursivos involucrados. Basándose en funciones Lyapunov, este trabajo prueba la estabilidad de los controladores auto-ajustables implícitos, combinando la estimación recursiva de los parámetros del controlador incluyendo el factor de olvido con el criterio de variancia mínima generalizada, aplicados a los sistemas variantes en el tiempo. Se considera que los parámetros del sistema cambian continua pero lentamente o cambian abrupta pero infrecuentemente. El análisis también se extiende al caso donde el modelo del sistema incluye ruido. Los principales resultados presentados en este trabajo son los teoremas que aseguran la estabilidad global del sistema en lazo cerrado, los cuales son probados en una manera mucho más directa comparando con resultados previos en el área. The important issue on self-tuning control includes the stability, performance and convergence of involved recursive algorithms. Based on a Lyapunov function, this paper proves the stability of implicit self-tuning controllers, combining recursive parameters estimation with a forgetting factor and generalized minimum variance criterion, for time-varying systems. The system parameters are considered to be changing continuously but slowly or changing abruptly but infrequently. The analysis is extended to the case where the system model is subject to system and measurement noises. The main results are the theorems which assure the overall stability of the closed-loop system, which are proved in a straight way compared with previous stability analysis results.

13. Improved Non-standard Discretization Methods for Nonlinear Dynamical Control Systems.

Author

Moreno Díaz, Roberto, Pichler, Franz, Quesada Arencibia, Alexis, Rodríguez-Millán, Jesús, González, Carla, and Patete, Anna

Abstract

In this paper we describe two modified versions of the Euler-Picard and Euler-Taylor-Picard discretization methods for nonlinear dynamical control systems. We use an upper bound for the absolute difference of each pair of consecutive Picard iterations, in the first case to control the number of Picard iterations, and in the second case to control the sampling frequency, while keeping the maximum allowed number of Picard iterations fixed. These non-standard discretization methods are used to support the construction of computer animated mimics of nonlinear dynamical control systems. [ABSTRACT FROM AUTHOR]
