摘　　要：针对三相六开关APFC的非线性控制,为进一步提高控制器的启动特性、稳定特性和负载特性,提出了一种电压外环和电流内环均使用变指数趋近律准滑模的滑模变结构控制策略。该控制策略采用变指数趋近律准滑模控制与反馈线性化相结合,实现控制系统的无超调量起动、输出电压纹波小及负载适应性好等特性。在Matlab/Simnlink环境下搭建仿真模型,与PI双闭环控制策略对比输出特性,通过对比说明了所提出控制策略的优越性。最后搭建了5 kW实验样机,利用实验结果进一步验证了所提出控制策略的正确性。Aiming at the nonlinear control of three-phase six-switch APFC,in order to further improve the starting characteristics,stability characteristics and load characteristics of the controller,a variable structure control strategy is proposed for both the voltage outer loop and the inner current loop,it used a variable exponential approaching law and quasi-sliding mode.The control strategy combines the variable exponential approaching law with quasisliding mode control and the state feedback linearization,it realizes the characteristics of the control system without overshoot,small output voltage ripple and good load adaptability.The simulation model is built in the Matlab/Simulink environm ent,and the output characteristics are compared with the PI double closed-loop control strategy.The superiority of the proposed control strategy is illustrated by comparison.Finally,a 5 kW experimental prototype is built,and the correctness of the proposed control strategy is further verified by experimental results.
