  1. 1. Nonlinear Identification and Control with Solar Energy Applications

    University dissertation from Uppsala : Institutionen för informationsteknologi

    Author : Linda Brus; Uppsala universitet.; Uppsala universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik; Automatic Control; Reglerteknik;

    Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pär Samuelsson; Uppsala universitet.; Uppsala universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; non-linear control; external carbon addition; multivariable control; cost-efficient operation; feedforward control; simulators; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik; Automatic Control; Reglerteknik;

    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.

  3. 3. Minimum-time sliding mode control of robot manipulators

    University dissertation from Örebro : Örebro universitetsbibliotek

    Author : Boyko Iliev; Örebro universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; minimum-time sliding mode control; sliding mode control; maximum-slope sliding lines; Takagi-Sugeno fuzzy systems; robot manipulators; reglerteknik; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Robot manipulators have a complex and highly nonlinear dynamics, accompanied with a high degree of uncertainty. These properties make them difficult for time-optimal control. The theory of sliding mode control can provide methods, able to cope with the uncertainty and nonlinearity in the system. READ MORE

  4. 4. Urban water management Modelling, simulation and control of the activated sludge process

    University dissertation from Uppsala University

    Author : Mats Ekman; Uppsala universitet.; Uppsala universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Abstract : During the last few decades, wastewater treatment processes in urban water management have become more and more efficient and complex. Several factors such as urbanization, stricter legislations on effluent quality, economics, increased knowledge of the involved biological, chemical and physical processes as well as technical achievements have been important incentives for the development of more efficient procedures for wastewater treatment plants.

  5. 5. Modelling and Control Methods with Applications to Mechanical Waves

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hans Norlander; Uppsala universitet.; Uppsala universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Abstract : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.
