基于模糊控制的锂动力电池快速充电技术研究与实现

摘要

锂动力电池充电过程和具有多变量、离散性和非线性等特点,传统的PID控制很难从它的数学模型出发进行控制,而模糊控制技术可以不要数学模型进行控制。将模糊控制技术应用于充电控制,提出了模糊PID的充电模型,并与PID控制模型进行对比。仿真实验证明该充电模型具有充电时间短、鲁棒性强等特点,具有重要的实际意义和推广价值。%The characteristics of Lithium battery charging process is multi-variable, discrete and non-linear. The traditional PID control is difficult to control from its mathematical model, but fuzzy control technology can control with the mathematical model. In this paper, we apply fuzzy control technology to charge control. The fuzzy PID charge model is proposed and compared with the PID control model. Simulation and experiment show that charge time is shorten in the charge model and the charge model is robust. It is significant in practice
