智能倒车系统中方向盘转角精确控制的实现研究

随着现实生活中因倒车而产生的困难和纠纷的不断增加,智能倒车系统的研究势在必行,而要实现汽车的高精度倒车,对方向盘转角的精确控制乃是关键技术之一.为此,本文提出了基于位置、速度、电流的三闭环控制方案,实验结果表明,该套方案能够实现方向盘转角控制无超调、响应快速且稳态误差小,可满足智能倒车系统的要求.

Realization of the Precise Control of Steering wheel Angle in Intelligent Car-Backing System

Due to the unceasing increase of difficulty and dissension brought by car-backing in our daily life, it's inevitable for the research of intelligent car-backing system, however, it!s one of the keys for the control of steering wheel!s angle displacement in the realization of cars precise backing. For this aim, a control project is raised in this paper, which is based on displacement close loop, velocity close loop and current close loop. The experimental results suggest that the control project can achieve such control performance as non over-adjustment, fleetly respond and low static error, which means that the project can reach the requirement of intelligent car-backing system.
