System Identification and Controller Design for Boiler and Heat Exchanger Set-Up

Jaya S. Lahane, Meera A.Khandekar

This paper is a case study, involving mathematical modeling of boiler and heat exchanger pilot plant by System Identification procedure. This is done by using System Identification Toolbox. Some fundamental control oriented issues such as System Identification, mathematical modeling and controller designing by using basic control strategies are discussed in it. First of all data is acquired from boiler and heat exchanger set-up. This data is used to obtain mathematical model with the help of System Identification Toolbox available in MATLAB. Transfer function model is obtained from System Identification and controller response is observed for this model. A conventional PID controller is designed and controller performance is studied
