Design and Control of Ideal Decoupler for Boiler Turbine System

This paper presents the application of state space model and controller design to a drum-type boilerturbine system. The step-response of a state space model is developed with the linearization of the nonlinear plant model. Then, the control performance of the PID controller is based on ideal decouple and multivariable system of the boiler. Because of several non-linearity of drum water-level dynamics, it is observed that the simulation with the response of the decoupled PID controller is more efficient than decentralized PID controller.
