自动离合器的变结构控制

Variable Structure Control of Automatic Clutch

针对机械自动变速汽车自动离合器的非线性、易受外部干扰和参数不确定性等特点,采用基于新型指数趋近规律的变结构控制实现自动离合器的有效控制。建立了自动离合器执行机构的动力学模型,并对其进行仿真。结果表明,与常规PID控制相比,这种新型指数趋近规律的变结构控制具有更好的控制性能。

Aiming at the features of non-linearity,being prone to external disturbances and parameters uncertainty of automatic clutch in AMT vehicle,a variable structure control based on novel exponential reaching law is adopted to fulfill the effective control of automatic clutch.A dynamic model for the actuator of automatic clutch is established and a simulation is conducted.The results show that this type of variable structure control adopted has better control performances than conventional PID control.
