模糊-PID在逆变电源中的应用

The Fuzzy-PID in the Inversion Electrical Power Application

逆变电源系统结构特殊且具有较强的非线性和参数时变性,尤其是在非线性负载下采用常规控制方法难以获得理想的控制效果。本文提出了模糊-PID控制方案,该方案将模糊控制与PID控制的优势相结合,实时地对PID参数进行在线调整。通过Mat- lab/Simulink对系统进行了仿真和验证,并与常规PID控制结果进行了对比和分析。

The inversion electrical power system structure is special, and has time the strong misalignment and the parameter denaturares,especially uses the conventional control under the misalignment load to obtain the ideal control effect with difficulty. This article proposed the fuzzy-PID control plan, this plan unifies the fuzzy control and the PID control＇s superiority, real-time makes the online adjustment to the PID parameter. Has carried on the simulation and the confirmation through Matlab/Simulink to the system,and has carried on the contrast and the analysis with the conventional PID control result.
