A robust control of contact force of pantograph-catenary for the high-speed train

In this paper, a simplified model to three degree of freedom (3-DOF) of the pantograph-catenary (PAC) system is represented. A robust control of contact force between the pantograph and the catenary for the high-speed trains using the fuzzy sliding mode controller and the additional compensator is presented. A PID outer loop in the control law is use then the gains of the sliding term and PID term are tuned on-line by a fuzzy system. The result of the simulation is fit for the actual phenomenon. Thus, the method of this paper is valid.
