Abstract: The present paper focuses on the development of a control system strategy on medium size industrial boilers (up to 1 MW) with the aim of having safe and efficient operation for the boiler itself. The class of the considered boiler is D-type water tube boiler. The basic plant model is based on Åström and Bell nonlinear dynamic model with simple adaptation due to specific geometries and physical constraints. The control system is mainly a combination of a pressure control loop and a three-element level controller. The pressure control loop here proposed consists of a gain scheduling PID control strategy to operate on heat power in order to keep the pressure at its desired value. The three-element level controller is a two-loop cascade control with feed forward water aimed at correcting the mismatch between the demand (steam flow) and feed water flow: level variation must be considered during this process because of the non-minimum phase behaviour of the level. Due to switching behaviour of gain scheduling approach, an adaptive control rule is also investigated in order to simplify the overall control structure and alleviate the adverse effects of the switching among many controllers in industrial applications.
