Chattering-Free Grey Sliding Mode Control for Discrete Time-Delay Systems with Unmatched Uncertainty

According to a class of discrete time-delay systemswith unmatched uncertainties and disturbance,a newchattering free least squares support vector machinegrey sliding mode control(LS-SVM-GSMC)law basedon Linear Matrix Inequality(LMI)is presentedEstimated value of external disturbance is obtained bygrey model,and output of LS-SVM is used forreplacing sign function of the reaching law in greysliding mode control(GSMC).The feasibility andeffectiveness of the LS-SVM-GSMC scheme aredemonstrated via numerical examples.As a result,byadopting LS-SVM-GSMC,chattering which is causedby grey reaching law is eliminated,and effect ofunmatched disturbance is reduced.
