摘要
运用系统动力学理论,建立了电动助力转向系统的状态空间方程。运用控制理论,分析了电动助力转向系统的补偿控制策略,并结合PID控制理论,在MATLAB/SIMULINK中建立了电动助力转向系统的仿真模型。对电动助力转向系统的补偿控制策略进行仿真研究。仿真结果表明,仿真模型的动态转向效果和回正能力得到了改善,解决了转向轻便性和路感的问题。
The state-space equation of electric power steering system was built by dynamics analysis theory.The compensation control strategy was analyzed by control theory,and combined with the PID theory we built the simulation model based on Matlab/Simulink.The compensation control strategy was studied,the simulation results showed that the steering dynamic effect was improved and the return ability was increased,also the problems of steering easiness and road feel were solved.
