摘要
在此研究了一种基于滑模变结构控制理论的三相PWM变流器直接功率控制方案,它利用滑模变结构控制系统具有良好的鲁棒性和动态响应性能等优点,克服了传统上PI控制算法的直接功率控制(DPC)系统抗扰能力差,参数整定复杂的缺点。在Matlab/Simulink环境中建立仿真模型,并做了相应的实验验证,仿真和实验结果一致,表明文中给出的控制策略是有效的。
A direct power control scheme for three-phase PWM rectifiers based on sliding-mode variable structure control theory is studied.It takes the sliding-mode variable structure control＇s advantages such as better robustness,better transient performance,to solve the conventional proportional integral control（DPC） problems such as high sensitiveness to external disturbances,and it is different to set parameters.The proposed controller for three-phase PWM rectifiers are modeled and simulated in the Matlab/Simulink environment,the experiment has also been made.The simulation and experiment has the same results,the results show that the proposed controller is an effective method.
