Abstract

Recent advancements in shipboard power system have focused on Medium Voltage DC Distribution System in Navy Ships. This system requires the use of high input to output voltage DC-DC converters to act as buffer between the MVDC bus and the load centers within the ship. The load lines to these converters which often involve other DC-DC converters and inverters, will be powering complex machinery and other sensitive systems. So, proper regulation and control of the DC-DC converter is necessary. This paper proposes a Fuzzy Logic Controller implemented on Buck Converter used in an MVDC Distribution System and compares the performance with a conventional PI controller. The simulation results using MATLAB illustrates the usefulness of FLC over the conventional PI controller.

舰船中压直流配电系统DC-DC变换器的模糊逻辑控制
近年来舰载电力系统的研究进展主要集中在舰艇中压直流配电系统。该系统需要使用高输入输出电压的DC-DC转换器作为MVDC总线和船舶内负载中心之间的缓冲区。这些转换器的负载线通常涉及其他DC-DC转换器和逆变器,将为复杂的机械和其他敏感系统供电。因此,对DC-DC变换器进行适当的调节和控制是必要的。本文提出了一种基于Buck变换器的模糊逻辑控制器,并将其应用于MVDC配电系统中,与传统PI控制器的性能进行了比较。MATLAB仿真结果说明了FLC相对于传统PI控制器的有效性。
