Abstract :
This paper proposes a novel state space model for the drum boilers with natural recirculation. This model uses the total mass and energy inventories of the boiler as the state variables, and has an affine structure in the control variables. A passivity based inventory controller is developed, which ensures the asymptotic stability of the closed-loop boiler system. Numerical simulations show the performance and efficiency of the passivity based controller design technique.
