FUZZY CONTROLLER DESIGN OF MULTI-MACHINES SYSTEM

Abstract

This work is devoted to a multi-machine system using vector control and fuzzy logic regulator. A six-phase asynchronous machine connected in series with a three-phase one fed by a single inverter and controlled independently. Thanks to the powerful means of calculation, which made possible the control of such systems and this allows its integration in applications where the constraints of space and weight require a particular. In a real machine, the stator and rotor resistances are altered by temperature and the inductances are altered by the magnetizing current values that change degrades the system performances. This problem is solving 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.
