A Design of an Adaptive Servo Control System Estimating the Internal Model

摘要

An adaptive servo control system estimating the unknown reference sig-nal model for a single-input single-output plant is proposed. The design is based on coprime factorization of the plant model over the ring of stable proper rational functions. An adaptive adjusting law is used to identify the unknown parameters of the reference signal model. Stability of the closed-loop system including the proposed adaptive servo system is proved.
