This work is devoted to a multimachine system using vector control and fuzzy logic regulator. A six-phase asynchronous machine is connected in series with a three-phase one fed by a single inverter and controlled independently is discussed in this paper. Thanks to the powerful digital signal processors, it is possible the control of such systems and this allows its integration in applications where the constraints of space and weight are of prime importance. In a real machine, the stator and rotor resistances are altered by temperature and the inductances are altered by the magnetizing current values and these changes if not incorporated in the control system block, the drive performance will degrade. This problem is solved by using fuzzy logic controller (FLC). Simulation results shows that FLC presents better performances and high robustness compared to the conventional proportional integral (PI) controller.
