| 摘 要： | 针对电动助力转向研究通常忽略控制策略对转向系统的影响,整车与转向系统之间是相互联系的问题,采用模糊PID控制和Carsim-Simulink联合仿真方法,在建立电动助力转向系统模型的基础上,根据不同工况下不同控制模式的需求,提出了多模式控制策略,应用模糊PID控制设计了电机电流控制器模型,并建立Carsim-Simulink联合仿真模型。仿真结果表明,建立的仿真模型是有效的,且所设计的控制策略能满足系统要求。

| Abstract: | Fuzzy PID control and joint simulation of Carsim-Simulink are applied for the problem that the study of electric power steering system ignores the influence of control strategy on steering system with the whole vehicle interconnected to the steering system.The multiple model control is proposed according to different working conditions of multi-objective control requirements and the motor current controller model is designed using fuzzy PID control to build the Carsim-Simulink joint simulation.The simulation results show that the simulation model is effective,and the control strategy designed better meets the control requirements of the system. |
