摘要
在Matlab/Simulink环境下建立了电动干式DCT轿车离合器操纵系统的仿真模型,并采用积分分离的PID控制算法对无刷直流驱动电机进行PID控制。在此基础上,对某型轿车进行了DCT系统的起步和换挡试验。结果表明,仿真结果与试验结果相符,验证了仿真模型的正确性,同时控制算法也满足系统控制要求,保证了DCT样车的平稳起步和换挡的平顺性。
A clutch operating system simulation model of car equipped with electrical dry DCT is established in Matlab/Simulink.PID control algorithm with integral separation is used in PID control to the brushless DC motors.On this basis,DCT system starting and shifting test of a passenger car is made.Test results show that the simulation results are identical with test result,verifying accuracy of the simulation model,meanwhile the control algorithm also satisfies the control requirement of the system,assuring steady starting and shifting smoothness of the car equipped with DCT.
