On Improving Transient Performance in Tracking Control for a Class of Nonlinear Discrete-Time Systems With Input Saturation

Abstract

Quick response and small overshoot are two desired transient performances of target tracking control. While most of the design schemes compromise between these two performances, we try to achieve both simultaneously for the tracking control of a class of nonlinear discrete-time systems with input saturation by using a composite nonlinear feedback (CNF) control technique. The closed-loop system with improved transient performance preserves the stability of the nonlinear part of the partially linear composite system.
