Proportional-plus-multiintegral stabilizing compensators for a class of MIMO feedback systems with infinite-dimensional plants

A method is presented for designing proportional-plus-multiintegral stabilizing compensators for a class of feedback systems with exponentially stable infinite-dimensional plants. These compensators enable the feedback system to asymptotically track polynomial inputs and suppress polynomial disturbances of corresponding order. When used in design, the effectiveness of the construction procedure presented can be increased considerably by combining it with the computational stability criterion and semiinfinite optimization. In this manner, the coefficient matrices of a compensator designed by the method can be further modified to ensure better feedback-system performance with respect to various performance requirements, without destroying stability, tracking, and disturbance-rejection properties. >
