一种新型军用电源智能充电机控制算法

军用电源充电机是一个多参数、时变的非线性系统,传统的PID控制算法难以在线调节达到优化充电曲线的目的。针对该问题,提出了一种基于模糊和免疫机理的自适应PID控制算法。该算法通过模糊免疫反馈机理对PID控制的比例系数进行实时调整,采用模糊自适应控制器对PID控制的微分、积分时间常数进行在线整定。仿真结果表明,该算法具有响应时间短、超调量小,鲁棒性强等特点,极大地改善了系统的适应能力,达到了优化充电曲线的目的。

A New Control Algorithm of Military Power Intelligent Charger

The military charger is a system of multiple parameters and time varying.The traditional PID control algorithm is difficult to adjust online,so it can not reach the purpose of optimizing the charging curve.To solve this problem,a self-adaptive PID control algorithm based on fuzzy and immune mechanism is proposed in this paper.The proportional coefficient of PID is adjusted in real time by fuzzy immune feedback mechanism in the algorithm.The differential and integral time constant of PID are set online by fuzzy self-adaptive controller.The simulation results show that the algorithm has the characteristics of short response time,small overshoot and strong robustness.The adaptability of the system is greatly improved,and the purpose of optimizing the charging curve is achieved by this algorithm.
