  2. 1. A Newton Method for Solving Non-Linear Optimal Control Problems with General Constraints

    Author : Henrik Jonson; Torkel Glad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Newton method; Non-linear; Control problems;

    Abstract : Optimal control of general dynamic systems under realistic constraints on input signals and state variables is an important problem area in control theory. Many practical control problems can be formulated as optimization tasks, and this leads toa significant demand for efficient numerical solution algorithms. READ MORE

  4. 2. 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

  5. 3. Tools for Autonomous Process Control

    Author : Anders Wallén; Institutionen för reglerteknik; []
