在分数阶微积分理论的基础上,研究了风力发电机变桨距液压控制系统控制策略,并运用Matlab的Simulink工具仿真,分析各个控制策略对风力发电机的变桨距液压控制效果。仿真结果表明,与整数阶PID控制器相比,该系统在分数阶PIλDβ控制器控制下整个闭环系统具备较好的动、静态性能,说明分数阶PIλDβ控制器控制性能的优越性。

The paper studies the controlling method of wind driven generator＇s variable pitch based on fractional calculus and uses Matlab＇s Simulink tool simulations to analyse the controlling effect of each control strategy on wind driven generator＇s variable pitch.Simulation Indicates that comparing with the Integer order PIλDβ cotroller,the closed loop system has good dynamic and static performance under the controlling of integer order PIλDβ controller.It shows the superiority of the Integer order PIλDβ cotroller.
