  1. 1. Modelling the Formation and Propagation of Orographic Rossby Waves

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Eskil Jonsson; [2017]
    Keywords : Global model; shallow fluid approximation; middle-high troposphere; potential vorticity conservation; Global modell; grund fluid approximation; mellan-övre troposfären; potentiell vorticitetsbevarande;

    Abstract : Orographic Rossby waves are the main mechanism by which the jet streams meander aroundthe Earth and have possibly far-reaching impacts on weather and climate (chapter 1). Hence,they are of particular importance to study and this project should serve as a starting point inwhat to consider when trying to model these waves. READ MORE

  3. 2. Model Predictive Control of Skeboå Water system

    University essay from KTH/Reglerteknik

    Author : Fredrik Gabrielsson; [2012]
    Keywords : ;

    Abstract : This thesis is a study of model predictive control of water levels and flows in a water system. The water system studied includes five lakes and six dams that are regulated manually by sluice-gates. The water is used in the papermaking process at Holmen Paper Mill in Hallstavik. READ MORE

  4. 3. Control of Water Content and Retention in Hydropower Plant Cascades

    University essay from KTH/Reglerteknik

    Author : Esbjörn Gullhamn; [2004]
    Keywords : Override Selector; State feedback Control; Saint Venant Equations; Hydropower Plant; Hydraulics Modelling.;

    Abstract : The discharge through a river hydropower plant must be controlled such that the water level at a pre-specified point close to the facility is kept within given bounds. The controllers used today have a somewhat demanding tuning and often create too much amplified, unnatural discharge variations resulting in unsatisfactory control performance. READ MORE

  5. 4. Physics Based Wave Generation for the Shallow Water Equations

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Oskar Nilsson; [2003]
    Keywords : Shallow water equations. Hyperbolic PDEs. Tank problem.; Technology and Engineering;

    Abstract : In this report we study systems governed by the Saint-Venant shallow water equations interacting with boundary conditions including control. We derive closed form formulas for the open-loop behavior. These formulas rely on first, second and third order approximations which are based on a perturbation that we develop. READ MORE
