Abstract :
This paper is concerned with adaptive control for discrete-time systems with time-varying uncertainties and time-varying delays in both state and control input. A new adaptive robust controller is presented based on the online parameter estimation and H∞ approach. A numerical example and simulation results are given to verify the effectiveness of the proposed controller.
