Mohamed I. Mosaad, Fahd A. Banakher · 2019
This paper introduces artificial neural network (ANN) controller for constant speed synchronous motors. The objective of the introduced ANN controller is directly control of the motor torque through three different control techniques namely, field control, armature control and field-armature control under load torque variations with minimizing the losses and consequently maximizing the efficiency of the motor. The idea behind the proposed controller is the injection of the appropriate field and armature voltages to directly control the motor torque with maximum efficiency. The presented neural controller structure is described by effortlessness and in practical by real time implementation. Results clearly demonstrate the adaptive property of the proposed scheme and ability of practical implementation. Moreover the ability of the three proposed control methods in direct torque control with the superiority of field-armature control method over both field control method and armature control methods.
