| 摘 要： | 利用瞬时值反馈控制可使电力电子变换器获得较好的动态响应和高质量的输出电压波形。本文针对SVPWM调制的三相航空静止变流器的系统模型特点,在d,q同步坐标系下,采用PI调节器实现了电压瞬时值反馈控制。为了抑制谐波对控制回路的影响,在控制回路中引入零相移低通有限冲击响应(FiniteImpulseResponce,FIR)数字滤波器。仿真和试验表明了该控制方案有效性。

| Abstract: | For obtaining fast response and high quality waveform of output voltage,power converters usually apply the instantaneous feedback strategy.According to the characteristics of the three-phase SVPWM aeronautical static inverter,this paper uses PI controller to implement instantaneous feedback in the d,q synchronous frame.To suppress the effect of harmonic on the control loop,a digital zero phase-shifted low pass Finite Impulse Responce Filter(FIR-filter) is applied.This paper also analyzes the frequency characteristics of the inverter,and introduces the design method of FIR-filter with the help of MATLAB in detail.The valid of control strategy is proved by simulation and experiment. |
