摘　　要：文章针对兆瓦级永磁同步风力发电机转子永磁体退磁振动问题,设计电磁执行器及时滞采样控制器以实现兆瓦级永磁同步风力发电机转子振动抑制控制.首先,根据永磁同步风力发电机转轴结构设计电磁执行器,完成电磁执行器电磁力模型的构建.然后,基于转子动力学理论,考虑转子永磁体退磁引起的不平衡磁拉力,构建了转子系统动力学模型.基于转子动力学模型,考虑实际传感器采样信号传输及控制器计算引起的时滞.利用Lyapunov稳定性理论并结合LMI处理方法,建立了兆瓦级永磁同步风力发电机退磁转子时滞采样振动抑制控制的条件.最后,通过兆瓦级永磁同步风力发电机参数仿真验算控制方案的有效性.The electromagnetic actuator for rotor vibration control of MW PMSWG is designed,and the time delay sampling control scheme of demagnetization rotor vibration is proposed.Firstly,the electromagnetic actuator is designed according to the shaft structure of the permanent magnet synchronous wind turbine,and the electromagnetic force model of the electromagnetic actuator is built.Based on the rotor dynamics model,considering the time delay caused by the actual sensor sampling signal transmission and controller calculation,using Lyapunov stability theory and LMI processing method,the conditions for periodic sampling and vibration suppression control of demagnetized rotor of MW PMSWG are established.Finally,the effectiveness of the control algorithm is proven by the parameter simulation of the MW PMSWG.
