A simple adaptive servosystem with a tuning parameter is considered for a linear continuous-time plant. A reference model is introduced for specifying a desirable transient response, while an integral compensator is used in order to cope with a constant disturbance input. Then, an adaptive control law is proposed, which achieves a suitable model following control independently of the selection of the integral gain. In other words, the disturbance rejection property can be tuned by the gain without changing the adaptive control law. This is a feature of the proposed simple adaptive servosystem.
