The regulation of the contact force between the pantograph and the overhead supply line (the catenary) has been recognized as one of the main problems to face with in order to speed up the velocity in high-speed railways systems [13, 16, 17, 19, 23]. Taking into account usual pantograph and catenary parameters, resonant modes are excited corresponding to train speed larger than 200

, and this can limit the railway system performance.
