Abstract

In this paper, we extend the exact model matching by observer-controllers to that by all two-parameter compensators and give an adaptive control scheme with free parameter Q using coprime factorization. The parameter adjustment law using a Riccati equation which guarantees the boundedness of the dynamic error system is proposed. Moreover, we construct the adaptive control system for a plant with output disturbances or unmodelled dynamics by designing the transfer function of error system and Q parameter to meet some desired robust performance properties
