Abstract:
An output-feedback direct adaptive control problem is considered for MIMO linear systems with polytopictype parameter uncertainties and disturbances. The objective is to make the system output follow the output of a system model and to attain guaranteed H¥ performance of the proposed adaptive control scheme. Sufficient conditions for closed-loop stability, model following performance, and achieving a prescribed bound on the H¥ disturbance attenuation level are derived, in terms of linear matrix inequalities. A numerical example, taken from the field of flight control, demonstrates the proposed method.
