Output-feedback model-reference sliding mode control of uncertain multivariable systems

Abstract: Abstract-This paper considers the robust output tracking problem using a model-reference sliding mode controller for linear multivariable systems of relative degree one. It is shown that the closed loop system is globally exponentially stable and the performance is insensitive to bounded input disturbances and parameter uncertainties. The strategy is based on output-feedback unit vector control to generate sliding mode. The only required a priori information about the plant high frequency gain matrix Kp is the… Show more

“…This method applies a floating gain to relieve the chattering problem, and the unknown uncertainties and disturbances were adaptively estimated and compensated by the updated sliding control method. Cunha et al [2] proposed an output-feedback model reference sliding mode control to solve the output tracking problem. The strategy of this method is based on an output-feedback unit vector controller to generate the sliding mode.…”
