Mutual influence between measuring devices and traction drives powered by battery

This paper deals with the elimination of mutual influence and undesirable couplings between the different systems placed on the experimental rail vehicle powered by the traction battery. This vehicle has a foursome mechanically independent drives and each drive has own DSP controller. The common power supply traction battery system and common superset control system are used for these vehicle drives. This configuration ensures the coordination of the traction forces between traction drives, which create one bogie with independently rotating wheels, provides the necessary energy flows but increases the complexity of the wiring arrangement from the viewpoint of the influence. This experimental vehicle is fitted with the sensors and the other measuring devices by the research reason of the effects of the control to running characteristics.
