基于滑模变结构理论的车辆主动横向稳定杆控制

摘要/Abstract

摘要： 为实现对车辆的侧倾控制，自主设计了主动横向稳定杆（AARB）装置。针对车辆在侧倾中存在的非线性、时变性特点，采用滑模变结构控制理论建立了滑模控制器从而实现对理想侧倾角的跟踪，并采用鱼钩与双移线转向工况进行了仿真试验。仿真结果表明，该主动横向稳定杆装置与传统被动横向稳定杆装置相比，能有效减小车辆的侧倾，同时具有良好反馈特性以，有利于驾驶员对车身姿态的判断，从而大大提高了车辆行驶的安全性与乘坐舒适性。

Abstract: In order to control the rolling of vehicle, AARB was designed. For nonlinear time-varying characteristics in the roll motions, a sliding mode controller was designed to track the ideal roll angle on the basis of the proposed AARB and the controller, steering simulations with the fishhook maneuver and double lane change maneuver were carried out to test the validity of the proposed control strategy in the aspect of roll controlling with AARB. Stimulations show that the method is effective in reducing the rolling of the vehicle and having good feedback to the driver for judging the vehicle body posture compared to the passive anti-roll bar. Therefore, the safety and comfort of the vehicle with AARB is greatly improved.

Key words: active anti-roll bar(AARB), roll, sliding mode control, safety
