摘要
为提高船舶混合动力系统中双向DC/DC变换器的性能,通过分析混合动力系统工作模式,设计出船舶混合动力系统双向DC/DC变换器仿真模型.基于此,提出该变换器模糊PID控制方法.采用单个模糊PID补偿环节实现了Bi Buck/Boost DC/DC变换器的稳定输出.仿真结果表明:模糊PID控制能有效提高系统抗干扰能力,保证双向DC/DC变换器具有良好的动态性能和稳态性能.
In order to improve the performance of bi-directional DC/DC converters in hybrid power system of ships,based on the analysis on the working mode of hybrid power system,a simulation model of the bi-directional DC/DC converter for ship hybrid power system is designed. A fuzzy PID controller of the converter is put forward based on the model. The output stability of Bi Buck/Boost DC/DC converter is realized by a single fuzzy PID controller. The simulation results show that the fuzzy PID controller can improve the ability of anti-jamming effectively,and ensure a good dynamic and steady performance of the bi-directional DC/DC converter.
