【摘要】 该文依据分析“汽车后部放大比率”(RWA)来设计和优化列车系统控制器。建立六轴汽车列车系统动力学模型 ,分析几种不同的控制策略 ,通过计算机仿真 ,以实现可接受的后部放大比率 (RWA)目标值。仿真结果表明可以通过前铰接点主动控制或前后铰接点同时控制有效地减少列车系统后部放大现象并实现安全行驶。更多还原

【Abstract】 This paper designs and optimizes controllers of the tractor/full trailer combination vehicle according to RWA. It presents a linear dynamics model of tractor/full trailer with six degrees of freedom. It compared several control strategies by RWA and simulations are performed under obstacle avoidance manoeuvers when the combination vehicle moves with a constant forward speed. It is found that active yaw controller at the front articulate point or active yaw controller at the front and the rear articulate points is effective in reducing RWA and can increase security of transportation.更多还原
