N2 - Nowadays, speed sensorless induction motor drives have been widely used in industrial applications. To improve the dynamic performance of the current loop, a sensorless robust predictive current controller combined with a speed adaptive full-order observer is presented in the paper. Based on the mathematical model of induction motor in discrete domain, the proposed controller is designed to replace the traditional PI controller. Compared with the PI control and traditional deadbeat predictive current control, the proposed method can significantly enhance the robustness of current feedback control. Meanwhile, a speed adaptive full-order observer is designed to obtain the motor rotor speed for the control scheme. The effectiveness of the proposed algorithm has been verified experimentally via a 3.7 kW electric drive system.
