ABSTRACT:
A robust model reference controller which supplies manipulated variables for controlling a multi-input multi-output process of the type which may not be modelled perfectly consists of a pre-compensator, a diagonal filter, and a post-compensator. The input signals to the robust model reference controller are first projected dynamically into decoupled signals by the pre-compensator. The diagonal filters then filter the decoupled signals individually. The filtered signals are projected back dynamically to the manipulated variables for the controlled process. The filter can easily be tuned to attain the optimal response of the closed-loop system with a given bound of model uncertainty.
