| 中文摘要:PWM整流器模型中的非线性特性给控制器的设计带来一定的困难，且随着对整流器性能的要求日益提高，传统控制在性能上已难以令人满意。对此提出一种新的双闭环控制策略，电压外环采用模糊PI控制，电流内环采用内模控制。模糊PI控制使系统具有更快的动态响应和更小的超调，电流环内模控制解决控制器过分依赖精确数学模型的问题，提高电流环的抗扰性能，并简化了控制器设计。理论分析和仿真对比验证了所提控制策略的正确性和可行性。 |

| Abstract:The nonlinear character of PWM rectifiers makes the design of controller some difficult. Facing the increasing requirements of PWM rectifiers, the traditional controller couldn't achieve satisfactory results. This paper proposed a new dual-loop control strategy with a hybrid fuzzy-PI voltage control as the outer-loop and an internal model current control as the inner-loop. The hybrid fuzzy-PI control makes the system have a faster responsiveness and a less overshoot, current loop adopting internal model control has solved the problem of excessive reliance on the precise mathematical model, improved the performance of anti-interference and simplified the design of controller. Theoretical analysis and simulation result has verified the correctness and feasibility of the control strategy presented. |
