摘要
通过对EPS系统的工作原理及其动力学特性进行分析,设计相位校正装置和模糊控制器对EPS系统进行控制,并建立电动助力转向系统和车辆动力学的数学模型,运用Matlab/Simulink软件搭建模型进行仿真。通过仿真得出方向盘力矩、转角、侧向加速度的时域响应关系曲线。仿真结果表明:在EPS系统中加入相位校正后,具有良好的稳定性。
Through the analysis of the working principle and dynamic characteristics of EPS system, phase correction device and fuzzy controller are designed to control EPS system, and the mathematical models of electric power steering system and vehicle dynamics are established. The model is simulated by using Matlab/Simulink software. The time-domain response curves of steering wheel moment, rotation angle, lateral acceleration, assistant moment and sensing moment are obtained by simulation. The simulation results show that the EPS system has good stability after adding phase correction.
