Time-varying controller design for input saturated systems

摘要

This paper presents a time-varying controller design for input saturated system whose poles are all in the closed left-half plane by introducing a time-varying parameter. The time-varying state feedback controller and the observer-based time-varying output feedback controller are both designed based on the parametric Riccati equation and parametric Lyapunov equation to ensure the exponential stability of the closed-loop system. The dynamic performance improvement of the closed-loop system is obtained by the designed controllers. The effectiveness and the usefulness of the proposed method are illustrated by the numerical simulation. (C) 2020 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
