Dead time processes are present in various industries at different levels. In certain situations, it is difficult to control such processes using conventional tuning techniques. Due to the need of precise control, robust tuning techniques are under development. This paper presents the design and comparative analysis of various PID tuning techniques for dead time process. The tuning techniques used to design PI and PID controller are Zeigler – Nichols, Tyreus – Luyben, Internal Model Control (IMC) and Extended Forced Oscillation (EFO) technique. The comparison is done on the basis of time response, frequency response (gain margin and phase margin) and performance indices (ISE, IAE, ITSE, ITAE).
