摘　　要：针对传统比例积分PI控制中响应速度慢、稳态性能差等问题,本文提出滑模比例谐振PR控制方法,其中电压外环采用滑模控制,电流内环采用PR控制。滑模控制提高直流侧电压的响应速度,PR控制改善交流侧电流正弦化程度。最后搭建Matlab/Simulink仿真及实验平台,验证文中所提滑模PR控制策略的有效性和可行性。仿真和实验结果证明滑模PR控制策略具有较好的鲁棒性和动态性能。In consideration of the problems in the traditional proportional integral(PI)control,such as slow response speed and poor steady-state performance,a sliding-mode proportional resonant(PR)control method was proposed in this paper,in which the outer voltage loop was under slidingode control(SMC)and the inner current loop was under PR control.The SMC can improve the response speed of the DC-side voltage,and the PR control can enhance the sinusoidal degree of the AC-side current.Finally,a simulation and experimental platform was established based on Matlab/Simulink to verify the effectiveness and practicality of the proposed sliding-mode PR control strategy.Simulation and experimental results showed that the sliding-mode PR control strategy had better robust and dynamic performance.
