摘要
对电动助力转向系统结构图和系统工作原理进行分析,推导出电动助力转向系统各个结构的数学模型。在数学模型基础上,基于Matlab/Simulink软件搭建电动助力仿真模型。进行了模糊和PID对转向系统进行联合控制。仿真结果表明:模糊PID联合控制具有良好电动助力特性,验证了控制策略的有效性。
The structure diagram and system working principle of EPS are analyzed, and the mathematical model of each structure of electric power steering system is deduced. On the basis of the mathematical model, the electric power simulation model is built on the Matlab/Simulink software. Fuzzy and PID are combined to control the steering system. The simulation results show that the fuzzy PID joint control has good electric assist characteristics, and the validity of the control strategy is verified.
