    STOICISM presented in 20th Nordic Process Control Workshop 2016 conference in Stockholm, Sweden

    as partner of the STOICISM consortium, Gomez Fuentes master student at University of Aalto, presented the poster “Simplified mechanistic model of the Multiple Hearth Furnace for control development” at the 20th Nordic Process Control Workshop 2016” that took place on 25 - 26 of August 2016 in Stockholm (Sweden). His contribution presents the simplified mechanistic model of a Multiple Hearth Furnace (MHF) for process control development. The full mechanistic model of the MHF is described, including its solving procedure. Based on the full mechanistic model, the simplified model is developed in the nonlinear Hammerstein-Wiener form, which defines a specific type of nonlinear state space models suitable for Model Predictive Control (MPC) implementation. The simplified model in addition aims to preserve description of the physical-chemical phenomena’s taking place in the furnace and to represent the nonlinear dependencies between the input and output variables using the steady state mass and energy balances. As the accuracy of the simplified model is crucial for the performance of the control techniques, the work aims to compare the simulation results of the mechanistic and the simplified model, which are compatible.

    Nordic Process Control Working Group was founded in Stockholm on October 24 1994, and through a Workshop that takes place every 18 months, aims to bring together people from academia and industry to discuss recent advances in theory and practice as well as map potential trends in the process control and the feasibility to test them with industry partners

    With around 40 participants from Sweden, Norway, Denmark, Finland, Italy and UK, the audience is a networking opportunity for process engineers, industry, academia and aims to promote the on-line monitoring as tool that improves understanding and has benefits in resource and energy efficiency.
