摘要
建立了电动助力转向系统主要部分的数学模型,根据助力原理设计了助力特性曲线,采用Matlab/Simulink工具箱建立了无电机助力、无PID控制算法助力和有PID控制算法助力的仿真模型。分析了3种模型的仿真结果,为进一步控制系统性能研究提供依据。
At first, the mathematic models of electric power steering system is built. The assisting characteristics curve is designed according to the assisting principle, and simulation models of systems with no power motor, no PID control assist and with PID control assist are built through Matlab/Simulink toolbox. At last, the simulation results of the three models are analyzed to provide reference for further study on the performance of control system.
