Commande Coopérative des Systèmes Monoconvertisseurs Multimachines Synchrones

Abstract : To make permanent magnet synchronous machines more attractive for aerospace (flight control actuators, braking systems, landing gear ...), it may be advantageous to reduce the number of power electronic modules used in the pooling. Many studies have been performed for systems composed of several machines and asynchronous traction primarily, but little concern synchronous machines. After considering various possible structures, this Ph.D. thesis presents an original study of a system consisting of two permanent magnet synchronous machines connected in parallel on a single shared inverter. These machines have characteristics identical or similar and must be driven at the same speed. The control structure chosen in this Ph.D. thesis is a master-slave : only one machine, called master machine is self-piloted, the other (the slave machine) operating in open loop. To ensure the stability of such a system, the timing of the two engines should always be respected. A control strategy, which selects which is the master motor, taking into account the variation of internal and external parameters of the system is then introduced. Under these conditions, the theoretical developments of the different variables are determined. To validate these results, an experimental process is established. The numerous results obtained in simulation and experiments are then used to confirm the theoretical results : whatever the mechanical or electrical parameters variation, system stability is always guaranteed. The additional case, when both machines move a mechanical load with a common rigid mechanical connection between two machines, is finally developed. An other required control strategy, the structure and the results are also presented in this Ph.D. thesis.
