Implementation of NARMA-L2 Neuro controller for speed regulation of series connected DC motor

Based on the nonlinear mathematical model of series connected DC motor (SCDM) system dynamics, the analysis and design of two speed controller presented, which are non linear PID and NARMA L-2 controllers. The speed response of motor is observed by giving reference inputs as speed and load torque in terms of step variation. The response of the system using NARMA L-2 Neuro Controller and conventional PID Controller are compared. It was observed that the NARMA L-2 Neuro Controller performance was better in terms of rising time, overshoot and steady state error over non linear PID Controller.
