Neuro-fuzzy controller for a permanent magnet synchronous machine singularly perturbed fed by a three levels inverter

In this paper, we present the control technique based on the singular perturbation technique controlled by a neuro-fuzzy regulator applied to the permanent magnet synchronous machine (PMSM). This technique applied to the PMSM conducts to a separation of the variables into disjoined subset or two separated models: one having a slow dynamics, and the other a fast dynamics. To ensure certain robustness to the decoupled control system based on these techniques, the control speed and the Id current is carried out by neuro-fuzzy regulators (ANFIS). A qualitative analysis of the principal variables evolution describing the behavior of the global system (PMSM-Inverter with MLI-Control) and its robustness is developed by several tests of digital simulation in last stage.
