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。
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 loaded with EPS system, moreover, compared to PID control strategy, fuzzy control strategy has the merits of faster response.
