CONTROL GLOBAL PD PARA SEGUIMIENTO DE POSICIÓN EN MOTORES A PASOS DE IMANES PERMANENTES

Maximiliano Valencia Moctezuma, Fortino Mendoza Mondragón, Víctor Manuel Víctor Manuel Hernández

Resumen


El control del motor a pasos de imanes permanentes es un tema de bastante interés en la actualidad ya que es bastante utilizado en aplicaciones que requieren precisión y por que puede ser controlado a lazo abierto. Pero en algunas aplicaciones el desempeño del motor a lazo abierto no es suficiente, lo que ha motivado al diseño de controladores a lazo cerrado que consideren la dinámica no lineal completa del motor. En este artículo se presenta el diseño de un controlador para el seguimiento de posición en motores a pasos de imanes permanentes que acciona una carga dependiente de la posición, además se prueba la estabilidad global del sistema a lazo cerrado utilizando el método directo de Lyapunov y se presentan resultados en simulación del controlador.

Palabra(s) Clave(s): estabilidad de Lyapunov, imanes permanentes, motor a pasos, seguimiento de posición.
