Este trabajo presenta el diseño de un controlador robusto H∞ para la estabilización de un Doble Péndulo Invertido (DPI). El modelo matemático del DPI es obtenido vía linealización del sistema diseñado en la Toolbox de simulación virtual SimscapeTM MultibodyTM de MathWorks. Se realiza una comparación entre el controlador incluido por defecto en la Toolbox mencionada y el controlador propuesto. La experimentación virtual demuestra que el algoritmo de control robusto H∞ exhibe un mejor desempeño en escenarios donde existen variaciones paramétricas como era de esperarse. En este sentido, la aportación de este trabajo es mostrar la síntesis del controlador y resaltar la importancia de la Toolbox que proporciona un entorno de simulación 3D para múltiples sistemas de ingeniería mecánica y robótica. De igual manera, resulta ser una excelente herramienta didáctica para el aprendizaje de los sistemas de control retroalimentado. Abstract: This paper presents the design of a robust H∞ controller for the stabilization of a Double Inverted Pendulum (DIP). The mathematical model of the DIP is obtained via linearization of the system designed in the virtual simulation toolbox SimscapeTM MultibodyTM of MathWorks. A comparison of the execution is made between the controller included by default in the aforementioned Toolbox and the proposed controller. Virtual experimentation shows that the H∞ robust control algorithm exhibits better performance in scenarios where there are parametric variations as expected. In this sense, the contribution of this work is to show the synthesis of the controller and highlight the importance of the Toolbox that provides a 3D simulation environment for multiple mechanical and robotic engineering systems. In the same way, it turns out to be an excellent didactic tool for the learning of feedback control systems. Keywords: robust control, double inverted pendulum, SimscapeTM MultibodyTM.Citas
