Performance Evaluation of Superheated Steam Temperature Control System based on Tuning Methods of Analog Controllers

Abstract

This paper explains the method of obtaining the best analog controller for a superheated temperature control system based on the least value of integral time weighted absolute error. The superheated steam temperature system is of fifth order model. This higher order model is converted into delay plus first order model by minimum area method. Analog controllers (P, PI, PID) are designed for Superheated steam temperature system by applying different turning methods. Simulations are performed by using the fifth order mathematical model of the system. The least value of integral time weighted absolute error decides the best analog controller.
