Comparison of boiler plant model and real plant responses based on proportional Integral controller

System model is very useful to study the response of a system for different input variations and for the control design schemes in both real time application and in the simulation. The concept of a model refers to entities varying from mathematical descriptions of a process to a replica of an actual system. The model of a boiler plant is derived and compared to the real plant response. In this paper the proportional and Integral (PI) controller applied for controlling the real and model of a boiler plant. The boiler plant model is derived based on the boiler plant dynamics. The experimental results show that the model developed able to represent the real boiler plant dynamic which proves by the similarity of the PI controller responses for both.
