Model parameter identification and sliding mode control of automobile clutch driven disk test machine

A method to design a composite sliding mode variable structure controller of clutch driven disk towing separation testing machine was proposed. Based on the simplified mathematical model, the system model was established using least square method. Moreover, on the basis of the system model, the controller which was composed of velocity feed forward, force feed forward and sliding mode control was used to control the system. The numerical simulation shows that the system has the good steady precision and dynamic characteristics by the proposed method.
