Este libro desarrolla, investiga, analiza y compara el control predictivo del Modelo (MPC) con la estrategia de control PID en el control de los sistemas de nivel industrial. Un método de control avanzado, MPC ha sido ampliamente utilizado y en una amplia variedad de aplicaciones en sistemas de control de procesos, utiliza un modelo de proceso explícito para predecir la respuesta futura de un proceso y resolver un problema de control óptimo con un horizonte finito en cada instante de muestreo. En este libro, en primer lugar un sistema de nivel de agua de tanque de circuito cerrado utilizando el modelo de estación de proceso de nivel móvil 3503 que es construido por Lab-Volt (Canadá) ha sido implementado en línea en modo de tiempo real utilizando el entorno MATLAB. A continuación, se ha linealizado el sistema para simplificar el análisis. Luego, se desarrolla una interfaz muy flexible, la adquisición inteligente de datos que podría ser utilizada con muy poco esfuerzo y será adecuada para cualquier proceso similar. Tanto el método de control MPC como el PID han sido probados para el proceso de Level, y compararon los resultados en términos de sobreimpulso, tiempo de asentamiento y error de estado estacionario bajo varias condiciones operacionales incluyendo retrasos de tiempo, también compararon la reacción de los controladores MPC y PID a la perturbación.
