摘要
结合EPS的结构和动力学特性,建立了EPS的动力学方程,采用PID控制和模糊控制方法分别对电机进行助力和回正控制,并结合三自由度的整车模型和Fiala轮胎模型建立了EPS整体仿真模型。分析了PID控制和神经网络控制对EPS整体系统的影响。
Based on the structure and the dynamic characteristics of electric power steering system,the dynamic equation of the steering system was established using PID and fuzzy control strategy to assist motor and steering reversal control respectively,and combined with three-axis car load model and fiala tire model,the EPS integral-simulation model was established.The characteristic of PID and neural networks control strategy affected by EPS system.
