Abstract

A new design concept for adaptive model-following control systems has been developed. The design procedure is based on the sliding mode property which exists in variable stucture systems. When the variable stucture system is operated in the sliding mode, the system response becomes lese sensitive to changes in the plant parameters, external disturbance and the effect of nonlinearities commonly occuring in control systems. The paper describes the application of the designed variable structure controller to an electromechanical system overcoming the effect of nonlinearities inherently present in the system. A systematic approach based on a pole assignment technique is developed for specifying the elements of the switching vector. The control problem is formulated and the results of a simulation study are presented.
