摘要 为提高双离合变速器的换挡过程平顺性,提出内模控制方法,提高离合器转速差的跟踪精度。设计转矩干扰补偿器来减小发动机端与负载端转矩扰动的影响,并基于平滑可微的参考转速差设计超前校正控制器。即使存在模型不确定与干扰,内模控制系统能维持稳定。仿真与台架实验结果表明,在不同参考输入与模型参数情况下,所提出的控制器均能达到较小的跟踪误差和平顺的换挡效果。 To improve the smoothness of the shifting process of the dual clutch transmission,an IMC control method is proposed to improve the tracking accuracy of the speed difference of the clutches.Torque disturbance compensator is designed to reduce the effect of torque disturbance from the engine side and the load side.Meanwhile an advanced correction controller is designed according to the smoothness and differentiability of the reference speed difference.The proposed IMC structure is stable despite of model uncertainties and disturbances.The simulation and bench test results show that the proposed controller can achieve smaller tracking error and smooth shift effect under different reference input and model parameters.
