  2. 6. Control of Nitrogen Removal in Activated Sludge Processes

    Author : Pär Samuelsson; Bengt Carlsson; Gustaf Olsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; non-linear control; external carbon addition; multivariable control; cost-efficient operation; feedforward control; simulators; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : More stringent requirements on nitrogen removal from wastewater are the motivation for this thesis. In order to improve treatment results and enhance cost-efficient operation of wastewater treatment plants, model based control strategies are presented. A Java based simulator for activated sludge processes (JASS) is presented. READ MORE

  4. 7. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

    Author : Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

    Abstract : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. READ MORE

  5. 8. Look-ahead Control of Heavy Vehicles

    Author : Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Abstract : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. READ MORE

  6. 9. PID Control, Design, Extension, Application

    Author : Helene Panagopoulos; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; PID control. Design. Optimization. Load disturbance rejection. Measurement noise filtering. Set point response. Robustness. Sensitivity. H-infinity control. Undamped process modes. Active control. Allpass and bandpass filter. Evaluation. Steam generator. Pulp and paper.; robotics; Automation; Automatiska system; robotteknik; reglerteknik;

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE

  7. 10. Fighter Aircraft Maneuver Limiting Using MPC : Theory and Application

    Author : Daniel Simon; Johan Löfberg; Torkel Glad; Jan Maciejowski; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model predictive control; flight control;

    Abstract : Flight control design for modern fighter aircraft is a challenging task. Aircraft are dynamical systems, which naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. READ MORE
