Abstract: This paper explains the tuning of superheated steam temperature system using Modified Zeigler tuning Algorithm. PID control has a wide range of applications in industrial control. Since many process plants use PID to control the dynamics involved in the process. It has been found possible to set satisfactory controller parameters from less plant information than a complete mathematical model. The fifth order model of super-heated temperature system is converted into first order model with delay using process reaction curve method. The analog PID controller is designed for superheated steam temperature system using Modified Zeigler tuning algorithm and Zeigler Nichols algorithm and results are compared.
