On Transient Improvement of Variable Structure Controlled Systems Using Multimodel Switching

摘要

This paper presents a multiple model/controller scheme for robustntracking of a class of nonlinear systems in the presence of largenplant uncertainties and disturbance. Each model is associatednwith a sliding mode controller, and a switching logic is designednto pick the model that best approximates the plant at each instant.nTheoretically, it is shown that the proposed control schemenachieves perfect tracking despite the existence of disturbance,nwhereas simulation results verify the improvement in the transientnperformance.
