摘　　要：针对自动离合器的非线性特性、易受外部干扰和参数不确定性的特点,采用动态滑模控制器实现离合器的有效控制,该控制器能有效缓解抖振现象并提高自动离合器的鲁棒性。为验证所采用控制器的有效性和鲁棒性,建造了基于dSPACE的自动离合器快速控制原型试验平台并进行试验。结果表明,与PID控制器和常规滑模控制器相比,所采用的控制器具有更好的控制性能。Aimed at the features of non-linear characteristics, being prone to external disturbances and parameter uncertainty of automatic clutch in AMT vehicle, a dynamic sliding mode controller is adopted to realize the＇ effective control of automatic clutch, with which the phenomenon of clutch chattering can be alleviated and the ro, bustness of automatic clutch can be improved. To validate the effectiveness and robustness of the adopted controller, a test platform for rapid control prototype of automatic clutch is built based on dSPACE and tests are conducted. The test results show that the adopted controller has better control performances compared to PID controller and conventional sliding mode controller.
