Parametric ARX Modeling of the Electrolytic Smelter Pot
March 25-March 27
ISBN: 978-0-7695-3593-7
The Anode effect that occurs in electrolytic smelter pot is responsible for gases such as PFC's. These gases contributeto the greenhouse effect, and in addition jeopardizes its productive capacity. From the voltage (output) and current(input) signals and based on Systems Identification Theory, the ARX models of the electrolytic smelter pot are built torepresent the steady state operation and the anode effect occurrence. After the simulations based on real anode effectsignal and algebraic properties of the transfer functions some models are validated based on the time response speed ofconvergence. The selected transfer functions of the electrolytic smelter pot are used to perform the steady staterepresentation and are oriented to predict the anode effect by the increasing of voltage. Therefore, this paper showsour latest investigation on parametric ARX models that represent the behavior of the plant in the neighborhood of itsinstability operation point.
