Modeling, Control and Analyze of Multi-Machine Drive Systems using Bond Graph Technique

In this paper, a system viewpoint method has been investigated to study and analyze complex systems using Bond Graph technique. These systems are multi machine multi-inverter based on Induction Machine (IM), well used in industries like rolling mills, textile, and railway traction. These systems are multi-domains, multi-scales time and present very strong internal and external couplings, with non-linearity characterized by a high model order. The classical study with analytic model is difficult to manipulate and it is limited to some performances. In this study, a "systemic approach" is presented to design these kinds of systems, using an energetic representation based on Bond Graph formalism. Three types of multi machine are studied with their control strategies. The modeling is carried out by Bond Graph and results are discussed to show the performances of this methodology.
