汽车AMT自动离合器的改进模糊滑模控制

Modified Fuzzy Sliding Mode Controller for Automatic Clutch of AMT Vehicle

提出改进的模糊滑模控制器(MFSMC)实现离合器的自动控制。MFSMC采用饱和函数和模糊自适应系统来缓解抖振现象并提高其鲁棒性;采用局部线性化技术减少MFSMC的模糊规则数满足自动离合器的实时性要求。模拟结果显示所提出的控制器具有快速跟踪预定轨迹、对参数时变和外部扰动具有鲁棒性等特点。

A modified fuzzy sliding mode controller （MFSMC） is proposed to control the automatic clutch. The controller uses saturation function and fuzzy adaptive system to alleviate clutch chattering and improve its robustness. The local linearization technology is adopted to reduce the number of fuzzy rules of MFSMC, meeting the realtime requirements of automatic clutch. The simulation results show that the proposed controller is effective in fast tracking and robust to parameter variation and external disturbance.
