摘要
汽车转向系统是影响汽车操纵稳定性、主动安全性和舒适性的关键部件。电动助力转向(EPS)是一种全新的汽车动力转向技术,通过建立EPS系统的动力学模型,得出系统的空间状态方程,再利用Matlab软件对系统在单位阶跃、脉冲和正弦输入作用下的转向角度跟随特性进行仿真分析。结果表明系统的角度跟随特性较好,为EPS的研究和设计提供了一个很好的依据。
The vehicle steering system is critical to the handling stability,initiative security,and comfort of the vehicle.Electric Power Steering（EPS） is a new technology of automotive power steering.Obtain the space state equation of the system by establishing the dynamics model of EPS.And then analyses the angle tracking characteristic of steering wheel on unit step function,unit impulse function and sinusoidal function input by the Matlab software.The results show that the angle tracking characteristic of the system is good,provide a better basis to research and design for EPS.
