摘　　要：为了提高三相PWM电压型整流器(VSR)的动静态性能,针对三相VSR传统PI控制器参数固定的缺陷,在传统双闭环控制策略的基础上将电压外环采用模糊PI控制器,在线调整PI控制器的两个参数,增强系统的鲁棒性。采用非正交坐标系下的SVPWM算法,与传统SVPWM相比简化了矢量算法步骤,更有利于数字化实现。最后利用MATLAB仿真分析了三相VSR的运行数据,通过比较可知,模糊PI非正交矢量控制系统与传统PI矢量控制系统相比具有更好的动态稳定性、跟踪性和抗干扰能力,仿真结果为此类硬件装置提供了改进设计的依据。Focusing on the defects of traditional PI controller of three-phase VSR-fixed parameter, this paper, based on the traditional double-closed loop control strategy, proposes to employ fuzzy PI controller for outer voltage loop in order to improve dynamic and static performance, which can improve the robustness and optimize the performance of the System. A SVPWM algorithm based on non-orthogonal coordinates is applied to inverter, and the algorithm steps are more simplified compared with the conventional SVPWM. The fuzzy PI based on non-orthogonal coordinates vector system is superior the conventional PI vector control system in dynamic stability, speed tracking and anti-interference by and MATLAB simulation analyzing the running data of three phase VSR, which provides the basis for improving the design of this kind of hardware device.
