Nowadays, the incresing speed of the train leads to a greater influence of some dynamic phenomena and, therefore, the control of the catenary-pantograph contact force gains more interest in order to increase the performance of current collection. The pantograph is used to carry out the current collection for the trains by means of the contact between this device and the overhead catenary line. The value of the force of this contact and its evolution along the railway is essential for a proper performance of the system because a loss of the contact will lead to arcing and electrically wear while too high forces will cause mechanical wear of both the catenary wires and the strips of the pantograph. In this paper, some configurations of PID-controller located at the frame of the pantograph are proposed. This PID-controller aims to minimize the variance of the contact force and the consumption of the energy supplied by the control force. Different configurations of the active control are determined according to this multicriteria optimization proposal using genetic algorithms.
