摘　　要：对无串联型DVR的逆变器控制策略进行研究,针对滤波电容电流内环、电压瞬时值外环的双闭环PI控制在快速性和精确电压补偿方面的不足,提出在双闭环PI控制的外环增加无模型自适应控制,形成复合控制算法,以提高控制器对信号的跟踪能力。通过Matlab/Simulink的建模仿真,表明该复合控制算法具有动态响应速度快、输出电压稳态精度高等特点。Non-series transformer dynamic voltage restorer （ DVR） control strategy is studied.In order to improve the speed and the steady state accuracy of voltage, current double closed loop PI con-trol, a model-free control was used as a compensation to form a composite control method.In the Mat-lab/Simulink to create simulation model, the simulation results show that the composite control method has great speed and excellent steady accuracy.
