Global modeling and simulation for analysis and design of a railway vehicle
2012
In this paper the equivalent global dynamic model of a railway vehicle is presented. The dynamic model is based on the following fundamental submodels: inverter, asynchronous motor, train, brake, controller. These submodels, even if interacting, are developed such that they can be modified independently. Moreover, they are characterized by a minimum number of parameters and by a relatively simple mathematical structure, in order to properly describe the corresponding system, to be identified by relatively simple dynamical tests and be used by a single specialist. It is also proposed a sufficiently robust minimum energy controller. Finally several simulation results are reported that demonstrate the validity and the usefulness of the proposed dynamic model and the controller efficiency.
