Active self-adaptive control of high-speed train pantograph

In this paper, in order to degrade the vibration of contact force between Pantograph and Catenary of high-speed railway, a new solution using Cylindrical Linear Induction Motor as active actuator is proposed. Based on the mathematical model of Catenary presented in the reference papers, the 2-degree Spring-Mass model of Pantograph-Catenary System is formed. Then get the self-adaptive control law by applying the Lyapunov direct model reference self adaptive control strategy. In the last part of this paper, the simulation results of active control are presented, the waveforms of contact force between Pantograph and Catenary under different vehicle speed indicate that the new method can suppress the fluctuation of contact force.
