Resumen:
This communication provides an approach for the application of PID controllers within a cascade control system configuration. Based on considerations about the expected operating modes of both controllers, the tuning of both inner and outer loop controllers are selected accordingly. This fact motivates the use of a tuning that for the secondary controller that provides a balanced set-point/load-disturbance performance. A new approach is also provided for the assimilation of the inner closed-loop transfer function to a suitable form for tuning of the outer controller. Due to the fact that this inevitably introduces unmodelled dynamics into the design of the primary controller, a robust tuning is needed.[ABSTRACT FROM AUTHOR] Copyright of International Journal of Computers, Communications & Control is the property of Fundatia Agora and its content may not be copied or emailed to …
