| 摘 要： | 介绍了DSP及重复控制技术在测试用交流电源中的应用。采用该控制方式的交流电源不仅能够输出频率幅值可调的正弦电压,而且能够输出周期性畸变电压。该电源采用数模混合控制及重复控制方法,数字部分实现高精度的波形发生器和电压有效值控制;模拟部分采用电压电流瞬时值控制,提高响应速度;重复控制可消除由非线性负载及周期性干扰引起的波形畸变。最后给出测试波形。

| Abstract: | In this paper,the application of DSP and repetitive control technology in AC power supply for test is introduced.The AC power supply based on this technology is able to produce the sine voltage,and it's frequency and breadth value can be adjusted.Furthermore,the seasonal aberrational voltage is produced.The power supply adopts D/A mixed control and repetitive control.The digital part realizes the high precise waveform generator and the control based on voltage virtual value.The analog part adopts the control based on current virtual value and improves the response speed.The repetitive control can eliminate the aberrational waveform because of nonlinear load and seasonal disturb.The test waveform is present at the end of this paper. |
