Abstract
The present study is focused on investigating the steady-state and transient responses of a DC servo motor controlled by the Proportional and Integral controllers. It is also studied how the P and I controllers affect the stability, error, and damping of the DC motor response. The DC servo motor responses are obtained experimentally using a servo trainer and a PI analog controller, and theoretically using MATLAB Simulink. It is found through the results that the P controller contributes to decreasing the input-output errors of steady-state and transient responses and tends to stabilize the system. It also speeds up the system response. On the other hand, the I controller tends to diminish the error but with sluggish response and affects the system’s stability with oscillations. Also, the Simulink results show that the optimized PI controller gains (Kp = 1.0363 and Ki = 1.9438) significantly reduce the overshoot and settling time. Through the present work, it is desired to obtain a stable response of the DC servo motor to the steady-state and transient input signals. The novelty of the present work is developing a PI controller-based nonlinear model for the DC servo motor speed control and optimizing the PI controller gains for the motor’s optimum performance.
