摘　　要：针对直驱式永磁同步风力发电系统风速多变、非线性和强扰动的问题,提出一种基于模糊控制和线性自抗干扰控制(Linear Active Disturbance Retection Control,LADRC)的混合控制方法。首先对线性自抗扰中的扩张状态观测器(Linear Extended State Observer,LESO)进行改进,提高对扰动观测的能力,同时利用模糊控制动态调整LADRC控制参数,增强系统的抗干扰能力和鲁棒性。仿真结果表明,与传统PI控制器相比,该方法能够更好地估计风速引起的转矩波动,准确跟踪额定转速,实现风能利用最大化。Aiming at the problems of variable wind speed,nonlinearity and strong perturbation in direct-drive permanent magnet synchronous wind power generation system,a hybrid control method based on fuzzy control and Linear Active Disturbance Rejection Control(LADRC)is proposed.Firstly,the Linear Extended State Observer(LESO)in linear self-jamming is improved to enhance the ability of disturbance observation,while the fuzzy control is utilized to dynamically adjust the LADRC control parameters to enhance the anti-jamming ability and robustness of the system.Simulation results show that compared with the traditional PI controller,this method can better estimate the torque fluctuation caused by wind speed,accurately track the upper rated speed,and maximize the wind energy utilization.
