  • In order to study the effects of active and semi-active technologies on pantograph performances, dynamic models for sliding mode active and semi-active control of pantographs are established. Based on the models, dynamic performances of the high-speed pantograph-catenary system under passive control, sliding mode active control, and sliding mode semi-active control are simulated using software Simulink. The influences of active control and semi-active control on the dynamic performances and current-receiving quality of the pantograph-catenary system are analyzed. The results show that the pantograph-catenary vibration can be suppressed effectively by the sliding mode active or semi-active control strategies, with a vibration magnitude reduction of 10% to 20%. The pantograph semi-active control is characterized by low external energy demand, unconditional stability of the control process, close effect to the active control, and will become an important method to improve the vibration performance of pantographs in high-speed conditions.
