摘　　要：针对三相脉宽调制(pulse width modulation,PWM)整流器控制系统的直流侧电压响应速率问题,提出一种基于模糊控制的电压快速响应控制策略.建立PWM整流器在qd坐标系下的数学模型,并进行欠驱动特性分析和控制策略研究,设计级联双闭环控制结构.利用部分反馈线性化策略,设计电流内环控制器,为提升直流侧电压响应速度,提出电压外环模糊控制策略.所提控制策略能够在0.05 s实现稳定,功率因数达到了0.99,提升了系统抗扰动能力,仿真结果证明了所设计控制方案的有效性.In response to the issue of the direct current(DC)voltage response rate in the control system of threephase pulse width modulation(PWM)rectifier,a fast voltage response control strategy based on fuzzy control is proposed.The mathematical model of PWM rectifier in a qd coordinate system is established,the underactuated characteristics are analyzed and the control strategy is studied,and a cascaded dual closed-loop control structure is designed.The inner current loop controller is designed by using a partial feedback linearization strategy and a fuzzy control strategy for the outer voltage loop is proposed to improve the DC-side voltage response speed.The proposed control strategy is able to achieve stabilization within 0.05 s with a power factor of 0.99,which improves the system's disturbance immunity.The simulation results prove the effectiveness of the designed control scheme.
