This paper presents an integral sliding mode controller with describing function method for active suspension systems. The proposed controller can occur a desirable limit cycle in the vicinity of switching surface, since the controller despairs perfect sliding modes. As a result, deterioration of the control effect due to the chattering in the high frequency range, such as increase in acceleration of the sprung mass related to the ride comfort, can be suppressed. The nonlinear switching control input in the proposed controller is based on the twisting algorithm. A necessity condition and a setting procedure for the parameters of the controller are demonstrated. A consideration of the robustness for the proposed method is presented. Finally, simulation results show the effectiveness of the proposed controller.
