Abstract

The tuning of controller is a big issue for a better system performance. This paper describes the modified method of measuring the delay time, time constant from the open loop response (S-curve) of the DC drive for step input. Later, using the same values of delay time and time constant, a modified tuning algorithm using Internal Model Control is proposed. Finally the time response of the DC drive with proposed control is compared with the Ziegler Nichols S-curve and modified S-curve algorithms in MATLAB/ Simulink environment. From the comparison, the proposed method shows a better performance than other methods in all aspects like rise time, peak overshoot and settling time.
