  1. 1. Large-scale dynamic optimizationusing code generation and parallelcomputing

    University essay from KTH/Numerisk analys, NA

    Author : Jose Rodriguez; [2014]
    Keywords : ;

    Abstract : Complex physical models are becoming increasingly used in industry for simulation and optimization. Modeling languages such as Modelica allow creating model libraries of physical components, which in turn can be used to compose system models of, e.g., vehicle systems, power plants and electronic systems.

  4. 3. Nonlinear Model Predictive Control for Combined Cycle Power Plants

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Anna Johnsson; [2013]
    Keywords : Optimization; Nonlinear Model Predictive Control; Extended Kalman lter; Modelica; Optimica; JModelica.org; Technology and Engineering;

    Abstract : This master thesis project serves to investigate the possibilities of Nonlinear Model Predictive Control (NMPC) using the example of enthalpy control of the BENSON HRSG (heat recovery steam generator) of a combined cycle power plant (CCPP). The general idea of NMPC is to solve an optimization problem, to nd the next control action, and this optimization problem is based on a model of the system. READ MORE
