Backstepping Controller Design for Pantograph-Catenary System [PDF]
IOP Conference Series: Materials Science and Engineering, 2018 This paper proposes an active control method to suppress the contact force fluctuation between pantograph and catenary for high-speed trains with external disturbance. First, fitted by using the non-linear least square method, stiffness of catenary is applied to the Pantograph-Catenary system(PCS).
