“…Wound-rotor induction motor (WRIM) has some specified applications that requires a high torque, adjustable speed drives, high inertia loads, so in order to improve the performance of WRIM use several methods of rotor control which include resistance and impedance [1]. The rotor of IM has 3-phase winding connected in star, and slip rings are connected to the rotor winding, these rings give the possibility of connecting external resistance (Rext) adding to the rotor that helps in speed control of WRIM [6]. The authors of [7] present a new method for soft starting of IM in rotor circuit that represented in a parallel combination of resistors, self-inductors and capacitors to obtain soft and higher starting torque (Ts) and starting current is limited.…”

Unlike 3-phase squirrel cage induction motor, starting-up of 3-phase wound rotor counterpart can be improved by adding an external resistance to the rotor circuit. Thus, leads to reduce starting current and increase starting torque. In this paper two controllers for 3-phase wound rotor induction motor have been proposed include conventional proportional integral derivative (PID) controller and the other based on artificial neural network (NARMA-L2). A comparison between these controllers has been conducted. It has been shown that starting torque of the motor has been improved, when utilizing the neural network controller compared to the conventional counterpart. It should be noted that MATLAB/SIMULINK has been used to implement both controllers.
