中文摘要：
在额定风速以下，风能转换系统需要通过控制发电机转速使风能的捕获率最大。根据风速的多时间尺度特性。建立风能转换系统的非线性机理模型，进一步得到其归一化误差的线性参数变化（LPV）系统模型；为获取最大风能捕获和减少机械振荡，在PI控制策略的基础上，利用基于LPV模型的增益调度控制器进行动态补偿。仿真结果表明：补偿后系统的功率系数和叶尖速比追踪其最优值的精度更高，鲁棒性更好，体现了更好的动态性能。
英文摘要：
When the wind speed is below the rated value, the generator is controlled to maximize the captured wind energy. According to multi-time scale of wind speed, the nonlinear mechanistic model for wind energy conversion system （WECS） is established. And then the Linear Parameter Varying （LPV） system model is released. Based on PI control strategy, the LPV gain scheduling control as dynamic compensation technology is taken. Simulation results show that the power coefficient and the tip speed ratio have much better accuracy and robustness in tracing their optimal value after compensation, and the generator can be controlled to maximize the captured wind energy below the rated wind speed.
