Abstract :
The present paper deals with the simulation and control design of the traction system of the VAL subway. The traction system is ensured by two DC machines connected in series. A common chopper supplies the armature windings and a double-chopper supplies the field windings. The novelty consists on modeling the physical system using Bond Graph, a structural formalism, whereas the control structure is deduced from the Energetic Macroscopic Representation which is a functional formalism. The combination of Bond Graph and Energetic Macroscopic Representation in the same simulation environment allows exploiting the advantages of both approaches. Simulation results are provided in order to illustrate the proposal and to analyze the performance of the closed-loop system.
