摘要/Abstract

摘要： 针对矩阵变换器输入侧电流易受到电网电压波动、负载变化的影响这一问题，提出了一种新的反步法控制策略，并应用于矩阵变换器上．通过 PARK 变换将矩阵变换器转化为 dq 坐标系下的数学模型，运用反步法控制策略设计了矩阵变换器输入侧电流的控制器，并和采用 PI 调节器的矩阵变换器进行了对比实验．仿真结果表明反步控制策略设计的控制器在负载变化及三相输入电源降落的情况下实现了对输入电流的快速跟随，谐波分析表明由反步法控制所带来的总谐波污染很小．将反步法控制策略用于数字信号处理器 TMS320F2812 进行编程实现，并进行带阻感负载的实验．结果表明矩阵变换器输入侧电流波形具有很高的正弦度．仿真及实验结果说明了反步控制策略的有效性、可行性．

Abstract: Aiming at the problem that the input side current of matrix converters can be easily affected by the power supply voltage fluctuation and the load change,a new back-stepping control strategy is proposed and implemented on a matrix converter.The matrix converter is converted into a mathematical model under the dq coordinate through the PARK transformation,and the controller for the input side current of the matrix converter is designed by adop- ting the proposed back-stepping control strategy and it is compared with that of the matrix converter with a PI con- troller by tests.Simulation results show that the controller using the proposed back-stepping control strategy can quickly follow the input currents under the conditions of both the change of load and the descent of three-phase power.Harmonic analysis indicates that the back-stepping control causes a low total harmonic distortion.Finally,the proposed back-stepping control strategy is encoded on the digital signal processor TMS320F2812,with an exper- iment involving resistance-inductance load being conducted.The results show that the input side current waveform of the matrix converter keeps a good sinusoidal characteristic.Simulation and experimental results demonstrate that the proposed back-stepping control strategy is both effective and feasible.
