摘要
根据电动助力转向系统的工作原理、控制模型、助力特性及控制策略,利用Matlab软件中simulink模块搭建基于模糊自整定PID控制的目标电流跟踪控制仿真模型,然后通过分析仿真结果得出模糊自整定PID控制能较好的满足EPS系统助力、操纵稳定、响应快的特性要求.对EPS控制系统研究具有一定的参考性.
According to the working principle,the control model,the assist characteristic of the electric power steering system and the control strategy,a target current control simulation model was built using the Simulink module of Matlab software based on fuzzy self- tuning PID control. The simulation results show that fuzzy self tuning PID control can better meet the characteristics requirements of the EPS system power,handling stability and fast response.
