Abstract:Aiming at the speed tracking control problem of high-speed train operation,a speed tracking control method based on auto-coupling proportional(ACPI)control is proposed.In this method,all disturbances such as the resistance and external disturbance of the train are defined as the total disturbance,and then the nonlinear model of the high-speed train is mapped into an equivalent linear disturbance system model.Based on this,a controlled error system is established,and the high-speed train speed controller is designed according to the ACPI control theory.The robust stability and anti-disturbance robustness of the control system are proved theoretically.The simulation results show that the maximum tracking error of the speed tracking using the active disturbance rejection controller is 1.5 times that of the self-ACPI controller when driving on a straight line.When driving on special routes such as curves,slopes,and tunnels,the tracking error of the speed tracking controller using sliding mode control is 105 times that of the ACPI controller.Simulation experiments verify the effectiveness and superiority of the control method in this paper.Compared with the speed tracking controller based on sliding mode control and active disturbance rejection control,the control method in this paper has the outstanding advantages of simple controller structure and few parameters.
