One of the relevant problems in high-speed train transportation systems is the regulation of the contact force between the catenary and the pantograph. The contact force should ensure a satisfactory permanent electricity feeding for the train. In this paper, a linear time varying (LTV) model of the pantograph-catenary (PAC) system is introduced. Since we cannot measure the current real states, we...
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...
