摘　　要：基于非线性PI理论,针对风力发电机组电动变桨距伺服系统中执行电机的非线性特性,提出了一种新的非线性控制方法。该方法基于对象的非线性模型,通过简单的非线性变换,把串励直流电机控制器的设计简化为线性系统问题。通过对变桨距电机负载所受驱动力进行了详细分析,进一步设计了控制器,在Matlab/Simulink环境下进行的数字仿真表明,此伺服系统具有良好的动态性能。A new nonlinear controller was proposed for the nonlinear character of electrical variable pitch servo system executive series of wind turbine,based on nonlinear PI theory. Depended on a non- linear mathematical model of the motor, the nonlinear control design was reduce to a liner control design by simple nonlinear transformation. The drive force of variable pitch wind turbine was analyzed in detail, and the controller was designed further.Digital simulations have been carried out by Matlah/Simulink software. The results showed that the servo system has a godd dynamic performance.
