摘　　要：首先对1.5 MW风力机液压独立变桨距系统进行数学建模,然后进行PID控制设计,最后对独立变桨距PID控制策略的各个工况进行仿真验证,结果表明:通过PID调节控制能改善风力机独立变桨距控制效果,提高动态特性,稳定功率输出。Firstly, the mathematical model of the hydraulic individual pitch control system of 1.5MW wind turbine is established, and then the PID control design is carried out. Finally, the simulation of the PID control strategy of the individual pitch control system is carried out. The results show that the control effect of wind turbine can be improved by adjusting the PID, which can improve the dynamic performance and stabilize the power output.
