A strategy of design for the controller and for a dynamic filter which compensates for disturbances is presented. The proposed algorithm has the robustness criteria which allows the controller to perform well under model uncertainties. The stability and dynamic performance of the control system is studied in relation to model-plant parameter mismatch. The algorithm is specially suited for time-delay processes. Simulation and experimental evaluation of the method is included in the paper.
