摘　　要：列车自动驾驶系统能提高轨道交通的效率,而它的主要功能是对列车速度的自动控制。与其他的一些控制对象不同,列车速度的自动控制除了要控制好速度以外,还需要考虑到乘客的舒适感。为此,文章设计了一种基于非线性PID原理的控制器,并通过MATLAB软件的Simulink模块进行了仿真。仿真结果表明,该控制器能在保证乘客舒适性的情况下有效跟踪目标速度信号。Automatic train operation can improve the efficiency of rail transit,and its main function is automatic control of train speed.Different from some other control objects,the automatic control of train speed not only needs to control the speed,but also needs to take the comfort of passengers into account.Therefore,a controller based on nonlinear PID principle is designed in this paper,and the simulation is carried out through Simulink module of MATLAB software.The simulation results show that the controller can effectively track the target speed signal under the condition of ensuring the comfort of passengers.
