The Pantograph-Catenary system(PAC) is the most crucial and vulnerable part in the high-speed train. During the high-speed movement of locomotive, the conventional passive control would cause various malfunction of the PAC system. Because the passive control does not have sufficient ability to avoid the dynamic variation of the contact force between carbon-plate and catenary wire. Therefore, this...
The high-speed train is typically powered by the catenary wire suspended from poles or towers along the rail. An important issue of the high-speed train's power supply is how to set the precise contact force between the pantograph and catenary wires in real time. It is not a trivial task to investigate the pantograph-catenary contact force regulation in engineering practice since the model of a pantograph...
This paper presents a robust adaptive fault estimation design method to solve the problem of actuator fault estimation for CCBII Braking System with disturbances and model uncertainties. The proposed robust adaptive fault estimator which is based on an adaptive observer can improve the speed of fault estimation. By transforming the system model into a special coordinate basis (SCB) form, we can structure...
