基于滑模变结构控制的电动助力转向系统

Electric Power Steering System based on Variable Structure with Sliding Mode control

针对汽车电动助力转向系统,提出滑模变结构控制方法,建立其运动方程,确定了滑模变结构控制器。台架实验结果表明这种滑模变结构控制器与PD控制器相比,其控制方法简单,同时具有更好控制效果。

A new method of Electric Power Steering System is presented, which is formed by the Variable Structure with Sliding Mode control, and the dynamical model and the Variable Structure with Sliding Mode controller are set up.The bench test results show that this Variable Structure with Sliding Mode controller is more simple than PD controller,and is more effective in control.
