An Enhanced Feedforward Compensation Speed Closed Loop Control Strategy for the Vacuum Pipelines High-Speed Maglev Train

Speed closed-loop control is a key operational control strategy for trains to achieve speed tracking, controllable position, and on-time parking. The vacuum pipeline maglev train aims at the high-speed operation, with the principle of safe, reliable. It should fully consider the precise control of traction operation. This article proposes an enhanced feedforward compensation control strategy. Firstly, the operation status of the train was analyzed, and established a motion model based on the traction and resistance. Under the constraints of train operation status, such as speed, acceleration, and position, and achieves high-precision speed closed-loop control through traditional PID control and enhanced feedforward compensation. Adjust and control according to the control strategy within the six adjustment intervals given for operating speed control error. Meanwhile, the strong robustness of the control strategy was verified based on artificial acceleration disturbance input.
