Diseño de control
Para diseñar y analizar sistemas de control modelizados en el entorno de Simulink, puede utilizar el software de Simulink Control Design.
Simulink Control Design amplía Simulink, permite encontrar puntos operativos y calcular las linealizaciones exactas de los modelos Simulink en diversas condiciones de funcionamiento. Simulink Control Design proporciona herramientas que permiten calcular las respuestas en frecuencia basadas en la simulación sin necesidad de modificar el modelo.
Simulink Control Design proporciona varios enfoques para ajustar los bloques de Simulink, como la función de transferencia y los bloques PID Controller. Puede utilizar estas técnicas y herramientas para hacer lo siguiente:
Ajustar automáticamente los bucles de retroalimentación que contienen bloques PID Controller o PID Controller (2DOF).
Ajustar gráfica o automáticamente los bucles de retroalimentación de sistemas SISO que contienen cualquier bloque ajustable de Simulink.
Ajustar los modelos de Simulink de sistemas de control con cualquier estructura para cumplir los objetivos de diseño de alto nivel, como el seguimiento de la referencia, el rechazo de perturbaciones y los márgenes de estabilidad.
