H∞ Tracking Control for a Class of Uncertain Time-delay Systems

Abstract

This paper considers the  H tracking control for a class of uncertain systems with time-delay and disturbance. The solvable sufficient conditions for the tracking control with state time delay are presented. The tracking controller is designed by using convex combination technique and Lyapunov functional method. The controller enables the system to meet the model reference  H tracking performance index. The delay-independent  H tracking control criteria is derived and formulated in the form of linear matrix inequality (LMI). A numerical simulation example is presented to verify the validity of the proposed method.
