A crucial system for the operation of high-speed trains is the pantograph catenary interface as it is the sole responsible to deliver electrical power to the train. The pantograph catenary system is a complex and nonlinear system. As a kind of model-free control, an auto disturbance rejection controller (ADRC) has unique advantages in dealing with internal and external disturbances. ADRC observes the disturbance of the system through its own extended state observer, and compensates it in the control algorithm, so as to obtain more accurate control effect. In this paper, ADRC is used for active control of the pantograph. Nonlinear PD combined control law is used to realize more accurate control of pantograph catenary contact force by compensating system disturbance, so as to improve current collection capabilities. The simulation results show that this active control technology is effective in improving the quality of current collection and has good robustness.
