Study and Sliding Mode Control of the Permanent Magnet Synchronous Machine

The PMSG permanent magnet synchronous machine is increasingly used in the industrial field thanks to its superior performance compared to other types of machines. this paper deals with the PMSG control. The modeling of the machine, the inverter and the PWM pulse width modulation control will be studied. In a first part we treat the vector command using PI regulator. In this part is interested in the design of a new nonlinear speed control. The proposed control is designed using a Backstepping control technique supplemented by the introduction of integral actions to improve its robustness. Using Lyapunov's stability theory, we show that trajectory tracking dynamics are asymptotically stable. Finally, a conclusion summarizes the main results obtained.
