Current limitation in the adaptive neural speed control of a DC motor

A simple design is proposed for a current limitation in the adaptive neural speed control of a DC motor. The design is based on using a current feedback from the output of the motor to the output of the ANN, and a simple logical operation between the end of the current loop and the input of the motor. Simulations are made of the performance of the controller with a current limitation and without a current limitation, for different types of reference speed trajectories. The control simulations are made for a DC motor with given parameters, and white noise is superimposed on both the rotor speed and the armature current at the output of the motor.
