摘　　要：楔形离合器在放大驱动力的同时放大了系统的输入误差,使得楔形离合器对参数与工况的变化更加敏感。提出一种自调整机制实时调整PID增益参数进行离合器转速差跟踪控制。该自调整机制通过李雅普诺夫稳定性理论进行推导,以确保控制系统的稳定性。在改变不同系统参数和运行工况的情况下,通过仿真和试验结果表明,所提出的控制器具有较好的鲁棒性能,提高了楔形离合器的换挡性能。The wedge clutch utilizes self-reinforcement feature to amplify the driving torque, however, the input variation is also amplified which makes the system more sensitive to variation of the system parameters and working conditions. In this paper, a self-tuning PID gain parameter is proposed to track the clutch speed difference. The Lyapunov theory is applied in the self-tuning adaptive control to ensure the control system stability. Finally, simulation and experiment demonstrate that the proposed controller has good robustness, improving the shift performance of the wedge clutch under different system parameters and operating conditions.
