ASPR Based Adaptive Output Feedback Control with an Output Predictive Feedforward Input for Continuous-Time Systems

Abstract

In this paper, almost strictly positive real (ASPR) based adaptive output feedback control with an output predictive control as a feedforward input is proposed for linear continuous-time systems. The method can design a stable and simple output predictive control based adaptive controller with higher control performance for uncertain systems. The method for discrete-time systems with two-degree-of-freedom control structure is expanded to continuous-time systems and the stability of the obtained control system will be analyzed in this paper. The effectiveness of the proposed method is confirmed through numerical simulations for simple second order uncertain system.
