“…In other words, we will try to improve the performance of the closed loop system by using the water flow rate information inside the controller. The mathematical formulation of the control design procedure was proposed in Kunze et al (2007) is recalled briefly for designing PID gain-scheduled controllers.…”

“…Therefore, a PID controller can be designed using linear programming. An extension to this method to design gain-scheduled controllers was presented by Kunze et al (2007) and is applied to design a gainscheduled PI controller for the condensing boiler where the gains are function of the requested water flow rate. The article is organized as follows: the process and control problem are described in Section 2.…”

This paper addresses the water temperature control in condensing domestic boilers. The main challenge of this process under the controller design perspective is the fact that the dynamics of condensing boilers are strongly affected by the demanded water flow rate. Two approaches are presented in this paper. First, a robust PI controller is designed that stabilizes and achieves good performance for closed-loop system for a wide range of the water flow rate. Then, it is shown that if the water flow rate information is used to update the controller gains, a technique known as gain-scheduled control, the performance can be significantly improved. Several models of a boiler in different water flow rate are identified in collaboration with Honeywell, and the effectiveness of the results are illustrated by simulation.

“…Moreover, an anti-wind up strategy was implemented to reduce the accumulated integral error of the controller when the output of the controller moved outside the SMV's range (22-40% of aperture). It is worth highlighting that other techniques to design the gain-scheduled controller could also be used, for example, the method proposed in [24]. Fig.…”

This paper addresses the water temperature PI control in condensing domestic boilers. The main challenge of this process under the controller design perspective is the fact that the dynamics of condensing boilers are strongly affected by the demanded water flow rate. First, a robust PI controller based on weighted geometrical center method is designed that stabilizes and achieves good performance for closed-loop system for a wide range of the water flow rate. Then, it is shown that if the water flow rate information is used to update the controller gains, through a technique known as gain scheduled control, the performance can be significantly improved. Important characteristics of these PI design approaches are that the resulting parameters are calculated numerically without using any graphical method or iterative optimization process and that it guarantees the stability of the closedloop. Significantly, simulation results have demonstrated that the proposed tuning techniques can perform better for set point changes and load disturbance than other available methods in the literature.
