摘要
针对逆变电源带非线性负载时波形失真的问题,建立了单相全桥逆变控制的仿真模型。系统利用电压电流双闭环反馈与重复控制相结合的控制方案来提高系统的动态响应性能和稳态精度,最后在MATLAB仿真平台下建立控制系统的仿真模型并对其进行仿真研究。仿真结果表明,重复控制能很好地消除周期性干扰及其它非线性负载引起的波形畸变。
In order to solve the waveform distortion problem of inverter with nonlinear loads,this article has established a simulation model of single-phase full-bridge inverter control.It proposes a control scheme combining double closed-loop feedback of voltage and current with repetitive control to improve the dynamic response and stable accuracy of the system.Finally the simulation model of controlling system has been established and studied with MATLAB.The simulation results prove that repetitive control can well eliminate the periodic interference and waveform distortion caused by other nonlinear loads.
