半挂汽车列车就是带有拖车的车辆,与一般车辆相比结构复杂,操纵稳定性不高。对于一个缺乏经验的驾驶者来说较难驾驶,而且当半挂汽车列车处于不稳定状态,让其恢复稳定状态很困难。本文针对半挂汽车列车的实际问题,提出了半挂汽车列车的理想模型。为了使实际车辆的输出信号和理想模型的信号相一致,采用数学解析方法,开发了半挂汽车列车自适应控制策略,并通过仿真验证了该控制策略的有效性。
Semitrailer trains are trailers with vehicles, compared with the general structure of the vehicle complex, the steering stability is not high. It is harder for an inexperienced driver to drive, and when the semitrailer trains are in an unstable condition, it is difficult to get them back to a steady state. In this paper, aiming at the practical problems of semitrailer trains, an ideal model of semitrailer trains is proposed. In order to make the actual vehicle output signal consistent with the signal of the ideal model, a mathematical analysis method is used to develop the adaptive control strategy of the semitrailer train, and the effectiveness of the control strategy is verified through simulation.
