| 摘 要： | 针对船舶直流区域配电系统中Buck变换器精确数学模型难以建立、经典控制系统设计困难的问题,提出了Buck变换器的模糊控制系统的设计方法和步骤,并建立了仿真模型。仿真结果表明,在Buck变换器输出电压的控制方面,模糊控制系统与经典PID控制系统相比,在超调量、震荡次数等控制指标上均有明显的优势。

| Abstract: | Aiming at solving the difficulty about building the model of a Buck converter of a DC zonal electric distribution system and designing the classic control system, this paper advanced a design method and the specific steps of a the fuzzy control system of a Buck converter. A simulation model was built and the simulation results shows that in the aspect of output voltage control of a Buck converter, the fuzzy control system is obviously superior to PID control system in indexes such as overshoot and the number of oscillation. |
