This work relates to the study of backstepping
control of the salient-pole double star synchronous machine drive fed by two three-level inverters. Indeed, it is a question
of carrying out a decoupling between stator current and electromagnetic torque, by introducing a backstepping control with an optimal torque working and by imposing
constant flux regime. Furthermore, to ensure a decoupled dynamic behaviour of the machine as in the case of a DC machine, a control of the rotor current has been introduced through a buck converter, feeding the excitation circuit. The obtained results are very satisfactory and reveal the effectiveness of the proposed approach.
