Design and Research on Control System of Active Power Filter Based on DSP

设计了基于TMS320F2812的并联型有源电力滤波器控制系统。采用DSP完成并联型有源滤波器控制系统的算法实现,谐波电流的提取和指令电流的计算采用ip-iq法,采用无差拍控制方法来实现补偿电流的产生,用MATLAB对系统进行了仿真实验,实验结果表明该控制系统具有良好的工作特性。

The digital signal processor TMS320F2812-based control system of shunt active power filter is designed. The control algorithm for control system of shunt active power filter is realized by TMS320F2812 processor, the ip-i4 principle is presented for the harmonic current extracting and the reference current generation. A deadbeat control strategy is used to control the producing of compen- sation current, A simulation study with the MATLAB on the system has been done, and experimental results show that the active power filter with the proposed control system is of well working characteristics.
