摘　　要：为了准确模拟液粘调速离合器电液比例闭环控制特性,使系统能达到稳定转速的目的,基于AMESim仿真软件构建液粘调速离合器PID闭环控制系统仿真模型。采用Ziegler-Nichols整定法确定了PID参数,研究了液粘调速离合器闭环控制系统输出响应特性,分析了PID参数对输出特性的影响。结果表明,该方法能准确地模拟液粘调速离合器PID闭环控制输出响应特性,PID参数对系统输出响应特性和转速稳定性均有较大的影响。通过PID闭环控制系统,液粘调速离合器可以达到恒转速控制,得到的仿真结果为控制器的设计提供了参考依据。In order to simulate the electro-hydraulic proportional closed-loop control characteristic of Hydro-viscous Clutch （HVC） accurately and obtain the steady rotation speed of output. The PID closed-loop control system simulation model for HVC was established with AMESim. The PID parameters were obtained by the method of Ziegler-Nichols. The closed-loop control system output response characteristic of HVC was researched. The effects of PID parameters on output characteristic were analyzed. The results indicate that the PID closed-loop control characteristic of HVC can be simulated accurately. The PID parameters have a great influence on output response characteristic and stability of rotation speed. The constant rotation speed for HVC can be reached by PID closed-loop control system. The simulations supply a useful theory for the controller design.
