摘要
离合器在起步接合过程中,通过油门开度及其变化率来推理驾驶员的操作意图。以驾驶员意图和离合器主、从动件速度差为控制参数,运用模糊控制理论,设计了车辆起步时磁粉离合器的模糊控制器,实现了起步接合过程中对磁粉离合器励磁电流的合理控制,使整车冲击度都满足相应指标,并使磁粉离合器的滑磨功较小。通过在MATLAB/Simulink中磁粉离合器的动力学建模,以整车模型为平台对起步控制策略进行了仿真试验验证,取得了较满意的效果。
During starting engagement of clutch,the driver operating intention can be ratiocinated by throttle percentage and its change rate. Based on fuzzy control theory,a fuzzy controller is designed to carry out the reasonable control to the field current of the magnetic particle clutch during vehicle starting so as to keep the vehicle impact under certain criterion and to decrease the work of slipping, in which the driver operation intention and rotation speed difference between driving and driven members are selected as control parameters. Through the simulation of dynamic model far magnetic particle clutch in MATLAB/ Simulink,the control strategies during vehicle starting are verified and sound results are obtained.
