| 摘 要： | 介绍了通过模糊控制器确定EPS系统(电动助力转向系统)助力特性的方法,建立了EPS系统模型及MATLAB/Simulink仿真模型,研究了常规PID控制策略和模糊控制策略,并在MATLAB/Simulink环境下进行了仿真。仿真结果表明,汽车加载EPS系统后,系统能更快的进入稳定状态,而且转向轻便性也得到了提升,另外,对比两种不同的控制策略,模糊控制策略反应时间更短、响应更快。

| Abstract: | The method to determine the EPS system (Electric Power Steering system) assisted characteristic by fuzzy controller is introduced, the EPS system model and MATLAB / Simulink simulation model are established, the conventional PID control strategy and the fuzzy control strategy are studied, and the simulation under the MATLAB / Simulink environment are carried out. The simulation result indicates that system can more quickly go into stable state and the steering agility is also improved after the vehicle is l... |
