摘　　要：针对直驱式永磁同步风电机组(permanent magnet synchronous generator,PMSG)矢量控制中的网侧电压、机侧功率波动问题,提出一种模糊自抗扰控制策略。在保证系统稳定的前提下将控制器应用于电压环,加快变流器能量转移至电网的速度,提高系统的暂态特性。最后,通过仿真深入对比分析该文所提控制策略和传统PI控制策略下直流母线电压和并网点电流、电压的波形。结果表明,该文所提结合扩张状态观测器的风电并网模糊控制策略的正确性和可行性。Aiming at the problem of grid side voltage and machine side power fluctuation in vector control of permanent magnet synchronous generator(PMSG),a fuzzy auto-disturbance rejection control strategy is proposed in this paper. On the premise of ensuring the stability of the system,the controller is applied to the voltage loop to speed up the transfer of converter energy to the power grid and improve the transient characteristics of the system. In the simulation study,the control performance of the proposed control strategy is also tested under various operating conditions using the Matlab/Simulink simulation platform. Analysis results verify the correctness and effectiveness of the control system.
