  2. 16. CPU Resource Management and Noise Filtering for PID Control

    Author : Vanessa Romero Segovia; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource management; embedded systems; real-time systems; multimedia; multicore; measurement noise; filtering; trade-offs; robustness; performance; SDU; noise gain; PID control;

    Abstract : The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. READ MORE

  4. 17. Modelling and control of activated sludge processes with nitrogen removal

    Author : Pär Samuelsson; Bengt Carlsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Abstract : Stricter legislations on nitrogen removal together with increasing wastewater loads have successively increased the need for optimization and control of activated sludge processes. The aim of this thesis is primarily to propose and illustrate methods for modelling and control of activated sludge processes, and thus possibly improve process efficiency. READ MORE

  5. 18. A Timely Journey Through the Cloud

    Author : Victor Millnert; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time Systems; Cloud; End-to-End Deadlines; Control Theory; Dynamic Networks; AutoSAC; Horizontal Scaling; Admission Control; Virtual Network Functions; Forwarding Chains; Network Calculus;

    Abstract : This thesis treats the intersection between two of the largest transformations we are seeing within our society today; the cloud and the Internet-of-Things (IoT). The aim of this thesis is to investigate different ways to model and control a network of cloud services so that timing-critical IoT applications can make use of them. READ MORE

  6. 19. Coordinated Control of HVDC Links in Transmission Systems

    Author : Robert Eriksson; Lennart Söder; Kjetil Uhlen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coordinated control; dynamic security; exact-feedback linearization; feedforward control; HVDC poser modulation; Electric power engineering; Elkraftteknik;

    Abstract : Dynamic security limits the power transfer capacity between regions and therefore has an economic impact. The power modulation control of high-voltage direct current (HVDC) links can improve the dynamic security of the power system. READ MORE

  7. 20. On the control of systems with input saturation or periodic disturbances

    Author : Kirthi Sarachchandra Walgama; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : This thesis deals with two important problems in control theory and practice. The first problem is the windup problem in controllers where there exist non-linearities between the controller output and the process input. READ MORE
