摘　　要：针对风力发电复杂非线性系统,在输入受限情况下,研究风力机如何实现变风速运行下的最大风能捕获,使其工作在最佳功率曲线,以提高风能利用率,并探究多风力机的协同控制问题。建立风力发电复杂非线性系统的Hamilton模型,设计预置控制器实现风力机的最大风能捕获。基于非线性扇区法的饱和函数处理方法,设计一种无记忆状态反馈控制器,实现多风力机的协同控制。实验结果表明在变风速运行且输入受限的情况下,风力发电机组能保持在期望的转速下运行,既实现了变风速条件下的最大风能捕获,又实现了抗输入饱和情况下的多机组协同控制。For the complex nonlinear system of wind power generation and under the condition of limited input,how to achieve the maximum wind energy capture under variable wind speed operation was researched.Consequently,wind turbine can work with the best power curve to improve the utilization rate of wind energy.The coordinated control of multiple wind turbines was explored.The Hamilton model of the complex nonlinear system of wind power generation was established,and a preset controller was designed to capture the maximum wind energy.Based on the saturation function processing method of the nonlinear sector method,a memoryless state feedback controller was designed to realize the cooperative control of multiple wind turbines.Experimental results show that under the condition of variable wind speed operation and limited input,the wind turbine can operate at the desired speed,which not only realizes the maximum wind energy capture under variable wind speed conditions,but also realizes the coordinated control of multiple wind turbines against input saturation.
