Different PID Tuning Rules for First Order Time Delay System

Abstract: This paper demonstrates an efficient method of tuning the PID controller parameters using different PID tuning techniques. The method implies an analytical calculating the gain of the controller (Kc), integral time (Ti) and the derivative time (Td) for PID controlled system whose process is modelled in first order plus time delay (FOPTD) form. In this Paper a First order time delay system is selected for study. The performance of PID tuning techniques is analysed and compared on basis of time response specifications.
