  1. 11. Parsing and Validation of Modelica Models Utilising Fault Diagnosis

    University essay from Linköpings universitet/Fordonssystem

    Author : Karin Lockowandt; [2017]
    Keywords : Model Validation; Modelica; Fault Diagnosis; Structural Analysis; XML; Dymola;

    Abstract : Models have become an indispensable tool within most industrial sectors and are used to reduce costs, enhance the performance of a system etc. The computer support within modelling is extensive, whereof the programming language Modelica is eminent, especially for multi-domain models.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Anthony Rousset; [2017]
    Keywords : Concentrated Solar Power CSP ; Direct Steam Generation DSG ; dynamic modelling; co-simulation; thermal-hydraulic calculation; two-phase flow; Ledinegg instabilities; control-command; regulation; PID controller.; Koncentrerad solenergi CSP ; Direkt ånggenerering DSG ; dynamisk modellering; co-simulering; termisk hydraulisk beräkning; tvåfasflöde; Ledinegg instabiliteter; kontrollkommando; reglering; PID-kontroller..;

    Abstract : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies.

  4. 13. Optimal control of clarifier-thickeners

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Sakari Teerikoski; [2017]
    Keywords : clarifier; thickener; modelling; simulation; control; cascade control; settling;

    Abstract : A computer model for a general clarifier-thickener has been made and used for comparing different strategies for control of such dewatering units through simulations. The model builds on widely acknowledged theory for modelling clarifier-thickeners - discretizing the settling PDE into a set of ODEs so that concentrations of solids at discrete depths inside the unit become the states of the numerical model - and it was written in the Modelica language using the modelling and simulation environment Dymola.

  5. 14. Relay Auto-tuners in Modelica

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Markus Björk; Robin Levenhammar; [2017]
    Keywords : Technology and Engineering;

    Abstract : The PID controller is by far the most popular controller for process control in industry today [Åström and Murray, 2008]. The combination of its relatively simple usage and its satisfactory results within several areas has gained its popularity [Visioli, 2006]. However, the tuning of the controller is crucial.

  6. 15. Structural Diagnosis Implementation of Dymola Models using Matlab Fault Diagnosis Toolbox

    University essay from Linköpings universitet/Fordonssystem

    Author : Petter Lannerhed; [2017]
    Keywords : Diagnosis; Structural Methods; Observer Construction;

    Abstract : Models are of great interest in many fields of engineering as they enable prediction of a systems behaviour, given an initial mode of the system. However, in the field of model-based diagnosis the models are used in a reverse manner, as they are combined with the observations of the systems behaviour in order to estimate the system mode.
