The separately excited Direct current (DC) motors with conventional Proportional controller is generally used in industry. This can be easily implemented and are found to be highly effective if the load changes are small. However, in certain applications, like rolling mill drives or machine tools, where the system parameters vary substantially and conventional PI or PID controller is not preferable due to the fact that, the drive operates under a wide range of changing load characteristics. Here in this paper a speed response is analyzed using PI control for a separately exited dc drive. The responses of steady state error, speed overshoot etc. are analyzed for a separately excited dc drive with small changes in load torque using the said controller. Performances of these controllers are verified by simulation in
