摘要

针VIENNA整流器的非线性特征,以及需要良好的动态性能和鲁棒性能,提出一种基于滑模变结构的VIENNA整流器的控制器;电压外环采用滑模变结构控制、电流内环采用误差迭代PI算法,改善三相VIENNA整流器的动态响应性能,达到无静差调节地目的。根据主电路拓扑建立VIENNA整流器的数学模型,设计了基于误差迭代PI算法和滑模变结构理论的VIENNA整流器控制器,仿真与实验结果表明该控制策略能达到控制目的,具有动态响应速度快和鲁棒性能强等特点,实验得出,超调电压超出参考值50 V时,到达稳定值的时间大约需要0.015 s。
        Aiming at the nonlinear characteristics of VIENNA rectifier and the need of good dynamic performance and robust performance, a controller based on sliding mode variable structure VIENNA rectifier is proposed. The voltage outer loop adopts sliding mode variable structure control and the current inner loop adopts error iteration. The PI algorithm improves the dynamic response performance of the three-phase VIENNA rectifier and achieves the purpose of no static adjustment. According to the main circuit topology, the mathematical model of VIENNA rectifier is established. The VIENNA rectifier controller based on error iterative PI algorithm and sliding mode variable structure theory is designed. The simulation and experimental results show that the control strategy can achieve the control purpose, with dynamic response speed and robust The performance of the rod is strong, and the experiment shows that when the overshoot voltage exceeds the reference value of 50 V, the time to reach the stable value needs about 0.015 s.
