新型主动转向系统的控制及仿真研究

Control and Simulation of A New Active Front Steering System

主动前轮转向系统存在着系统参数变化、路面干扰等不确定性因素;针对这一问题,文章在深入研究新型主动转向工作原理的基础上,设计了新的数字控制器,并进行了控制仿真和实验;实验结果表明:所设计的数字控制器能获得较好的抗干扰性和转向轻便性,同时提高了转向系统的稳定性。

There are many uncertain factors including a variety of system parameters and the road surface disturbance are existed in the active front steering system. Aiming these problems, a new digital controller is proposed based on the new active front steering structure. Simulation and experiments results show that this controller can lighten steering torque and restrain disturbing signals which come from out side, the stability o[steering system is also improved.
