摘要
分析了车辆防抱死制动系统的滑模变结构控制,提出了防抱死制动系统的模糊滑模变结构控制方法,根据滑模切换函数及其导数对滑模控制量进行模糊划分,形成二维模糊控制规则表。对切换函数及其导数采用动态模糊划分,以提高系统控制的敏感度。对单轮系统车辆的仿真表明,模糊滑模变结构控制方法既能缩短响应时间,也能抑制系统颤振。
Based on the analysis of sliding mode control of vehicle ABS（anti-lock brake system）, a fuzzy sliding mode control approach for ABS was presented. To restrain chatter of the system, the control value of sliding mode controller was partitioned with fuzzy way according to switch function and its derivative which denoted the distance between current state point and switch surface and velocity of state point moving to the surface respectively. The fuzzy partition of switch function and its derivative was dynamic ,which can enhance sensitivity of the control system. The simulation results of single wheel vehicle show that the presented method can shorten the response time and the chatter is restrained.
