Modelling of Ionization Current in a Flame based on Hammerstein Models

Controller based on ionization current measurement are state of the art in the field of wall hung gas boilers (WHB). They are used to control the gas-air ratio of the combustion. The underlying ionization mechanism is a complex three-dimensional problem. Therefore, it is a difficult task to describe this system with a white-box model for simulation and controller design. This paper investigates a ...
