1B21 Modeling and Robust Control of a High Speed Train Pantograph(The 12th International Conference on Motion and Vibration Control)

抄録

For high-speed trains, active control of the pantograph is crucial technology to collect electrical current from the overhead contact wire. In this paper, a mathematical model of the pantograph-catenary system is developed to design a controller, and then a sliding mode controller is proposed to regulate the contact force in the presence of variation in the equivalent stiffness of the catenary system. Although the proposed controller is based on the standard sliding mode control theory, some modifications are made from a practical point of view, in particular necessary sensors for its implementation.
