| 摘 要： | 三相电压型PWM整流器(VSR)用于AC/DC/AD系统前端整流器时,由于PI控制的滞后性及其比例积分系数对系统参数的敏感性,很难在四象限运行中保持良好的动态性能和鲁棒性。考虑到VSR本身非线性的特点,提出了一种基于同步旋转坐标系的双闭环滑模变结构控制算法,在MATLAB/SIMULINK环境建立了仿真模型,对滑模算法和PI算法进行了对比仿真。结果表明,较之PI算法,滑模算法具有更好的动态响应。

| Abstract: | AC/DC/AC system in which three-phase voltage source PWM rectifier (VSR) is adopted as the front-end rectifier can hardly obtain good dynamic performance and robustness in four-quadrant operation due to the lag of PI regulator and the sensitiveness of its proportional and integral gains to system parameters. Considering the nonlinear characteristic of VSR, a sliding-mode control algorithm based on synchronous rotating reference frame was proposed. The whole system was modeled and simulated in MATLAB/SIMULINK to obtain comparison between sliding-mode and classical PI control. The results show that the sliding-mode control possesses preferable dynamic response compared with PI regulator. |
