摘要
为了提高高速列车的控制精度,设计了基于高速列车多质点模型的自适应跟踪控制策略,实现了对给定速度曲线的渐近跟踪。首先,通过对高速列车进行受力分析,得到考虑非线性阻力和相邻车厢间的车间作用力的高速列车多质点动力学模型;然后,充分运用自适应方法善于处理系统不确定性的能力,设计了高速列车直接自适应控制策略,实现了其对给定速度曲线的渐近跟踪;最后,基于CRH380A型高速列车多质点模型进行了仿真验证,结果表明所设计的多质点自适应控制策略对给定速度曲线的跟踪具有较高的精度,为高速列车的智能驾驶奠定了基础。
To improve the control accuracy of high-speed trains,this paper develops an adaptive tracking control scheme for the multiple point-mass model of high-speed trains to achieve asymptotic tracking of a given velocity trajectory.Firstly,by analyzing the forces on the high-speed trains,a multiple point-mass dynamic model of high-speed trains is obtained,in which the nonlinear resistances and the workshop forces between adjacent cars are considered.Then,a direct adaptive control strategy is derived to realize track of a given velocity trajectory,by fully using the capacity of adaptive control in handling uncertainties.Taking CRH380A high-speed train as an example,the simulation verifies that the multi-point adaptive control strategy has high accuracy in tracking the given speed curve,and can meet the requirements of the high-speed train’s intelligent operation.
