Abstract :
A new backstepping controller is designed for two different speed sensorless induction motor, based on measurements of stator current. As in field-oriented control scheme, the backstepping analysis generates references for magnetizing flux component and for the speed component of the stator current. The control algorithm is proposed for replacing the existing PI controller to obtain high performance motion control systems, for the speed, flux and currents control loops. Also, the control comes along with a through proof derived based Lyapunov stability theory. Open loop estimator and closed loop observer are used for this purpose and compared in term of their robustness against rotor and stator resistances variations. Simulation results are provided to judge the consistency, effectiveness and performances of this control technique.
