Información del artículo
Resumen
El presente artículo muestra la aplicación de los controladores PID de dos grados de libertad, a un conjunto de modelos con dinámicas diversas, representativos de procesos en el ámbito industrial. Este tipo de estructura de control permite hacer frente tanto a las perturbaciones en el sistema, como a los cambios en la señal de consigna. Se presentan posibles formas de conseguir estos objetivos de control, así como técnicas para obtener sintonías que optimicen índices específicos, que contemplan el rendimiento y el esfuerzo de control del lazo. En particular se describe el procedimiento utilizado para la solución del problema propuesto por el Grupo de Ingeniería de Control del CEA, del “Benchmark” de Sistemas para Controladores PID.
