Intelligent PI Controller for Speed Control of D.C. Motor

An Intelligent PI Controller has been developed for speed control of separately excited D.C. Motor by exploiting the features of Artificial Neural Networks (ANN). The aim of the proposed schemes is to improve tracking performance of separately excited D.C. motor as compared to the conventional (PI) control strategy. Performance of these new controllers has been verified through simulation using MATLAB/SIMULINK package. In the present work the ANN concept is applied for both control strategies i.e. current and speed for D.C. separately excited motor. Intelligent PI Controller enhances the performance and dynamics of the D.C. motor in comparison to conventional PI controllers. 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.
