Abstract— This paper presents an enhancement of stability and accuracy of the separately excited DC (SEDC) motor under the effect of the external disturbances (dynamic load changes) and noise by using conventional Proportional Integral (PI) and Proportional Integral Derivative (PID) controllers. DC machines are characterized by their versatility. The aim of the proposed schemes is to improve tracking performance of separately excited DC motor as compared to the Proportional Integral (PI) control strategy. Performance of these new controllers has been verified through simulation using MATLAB/SIMULINK package. In this paper, The SEDC motor model is chosen according to its good electrical and mechanical performances more than other DC motor models. The modeling and simulation of the SEDC motor was done using the software package MATLAB/SIMULINK. A speed controller has been designed successfully for closed loop operation of the SEDC motor so that the motor runs very closed to the reference speed. The simulated system has a fast response with small overshoot and zero steady state error. Excellent results added to the simplicity of the drive system, makes the ANN based control strategy suitable for a vast number of industries, paper mills etc.
