On an Adaptive Model Following Control System for a Plant with Dead Time

Abstract

This paper deals with an adaptive model following control system. In model reference adaptive control systems, a system which has adaptive action by signal composition is called an adaptive model following control system. Also, such a control system is called a passive adaptive control system. In these systems, an adaptive compensator having inverse characteristics of the model is approximately realized using an adaptive observer. In this paper, an adaptive model following control system using a combination of a Smith predictor and a passive adaptive control loop is proposed and discussed for systems with dead time and varying plant parameters. Stability and adaptation of these systems are discussed. Moreover, simulation results obtained for some examples are shown.
