摘要
改善数字电源控制精度和动态性能是目前数字电源研究的热点;基于MATLAB仿真研究了数字电源的模糊自适应PID控制算法;仿真结果表明自适应模糊控制的数字电源具有超调量小、稳定时间短、静态误差小的特点。
Nowadays,it is popular to research how to get better control accuracy,especially in the dynamic conditions.In this paper,the self-adaptive fuzzy-PID control laws were applied to the switching mode power supply.The results of the simulation is better than the regular PID control,that is to say much smaller overshot,much smaller rise time and little quiet error.
