摘要：AbstractWhen increasing the power, Multiphase Induction Machine (MPIM) offer, compared to the three-phase induction machine, an interesting alternative reduction of the current switched by inverter and at the windings, allow a torque reduction ripples. In addition, the number of phases more than three offers increased reliability by allowing the machine to continue to operate even if one or more phases fail, which favors its use in applications requiring more reliability such as electric cars. Most previous works have focused on the speed/flux regulation of multiphase machine, ignoring the open phases fault. This paper present the robustness of backstepping technique for multiphase induction machine control taking account of open phases faults. The proposed robustness study involves a multi-loop nonlinear controller designed to meet the two main control objectives, i.e. tight speed regulation for a wide range speed-reference variation and rotor flux regulation. The feedback control convergence is formally analyzed using Lyapunov technique and its performances are illustrated by simulation.
