摘　　要：针对大型风力机比例阀控液压马达变桨距位置控制系统进行仿真研究。首先,建立了比例阀控马达系统数学模型,确定系统的特性。然后,选取适当的风速模型,并通过风速与变桨距负载的关系获得系统负载的目标参数。最后,对比例阀控液压马达变桨距位置控制系统进行仿真研究,建立了主要元件与系统的AMESim仿真模型,通过仿真分析验证了比例阀控液压马达系统用于大型风力机变桨距位置控制的可行性。The simulation of wind turbine pitch position control based on proportional valve-controlled hydraulic motor system was formed. Firstly, the mathematical model of proportional valve- controlled hydraulic motor system was built and the system characteristic was confirmed. The parameters of the system were confirmed through the selecting of proper wing model and understanding the relationships between the wind speed and the pitch load. Finally, the simulation model of proportional valve-controlled hydraulic motor position control system was established by AMESim and the feasibility was verified.
