摘要
文中针对传统蓄电池充电时间长,具有过冲、欠冲、析气的问题,结合模糊控制技术,提出了一种模糊自整定PI参数的方法对电动汽车铅蓄电池充放电电压进行控制,并考虑了温度的影响,在MATLAB/Simulink仿真平台上对电压控制系统进行仿真。仿真结果表明,加入了模糊PI控制的系统具有更好的动态响应特性和稳态特性。自整定PI模糊控制器具有控制精度高,超调小,动态性能好的特点。
Based on traditional battery charging time long, overshoot and undershoot, analysis the problems, combined with the fuzzy control technology, this paper proposes a method of fuzzy self-tuning PI parameters to control electric car lead battery charge and discharge voltage, and considering the influence of temperature and voltage control in MATLAB/Simulink platform system simulation. The simulation results show that joined the fuzzy PI control system has better dynamic response and steady state characteristics. Self-tuning PI fuzzy controller has high control precision, small overshoot, good dynamic performance characteristics.
