Abstract

This paper presents a new method for adaptive control of time-varying plants with time delay. It combines the model reference adaptive control (MRAC) strategy with quasi-sliding mode variable structure control strategy, and obtains a good control quality. Furthermore, a quasi-sliding VS strategy for discrete-time is also derived so that the algorithm can be used to realize the numerical control. The theoretical and simulation results show that the presented algorithm is valid and efficient
