改进模糊PID参数的电动汽车动力控制系统研究

Research of Electric Vehicle Power Control System Based on Improved Fuzzy PID Parameters

在传统PID控制策略的基础上,引入逻辑模糊控制思想,通过逻辑模糊法则对PID控制参数KP、KI和KD进行优化.仿真结果表明,采用优化的PID控制参数,可以使电动汽车具有良好的起动加速性能、运行性能、爬坡性能以及车速突变控制性能.

This paper introduce Fuzzy logic control thought which KP, KI and KD of PID control parameters were optimized by the fuzzy logic rule on basis of traditional PID control strategy. The simulation results show that the control parameters of PID are optimized can make electric vehicle good starting acceleration,running,climbing and speed change control performance.
