  1. 21. Estimation of the Dynamic Relative Gain Array for Control Configuration Selection

    Författare :Ali Kadhim; Hamid Reza Shaker; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : The control of multi-input multi-output systems (MIMO) is more difficult than for single-input single-output systems (SISO) due to the multitude of input-output couplings. Coupling, simply means that a change in any input leads to changes in many outputs. LÄS MER

  3. 22. Towards the Development of Efficient Cooling Control Strategies for Edge Data Centers

    Författare :Amirreza Zaman; Wolfgang Birk; Dina Shona Laila; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : Data centers, including edge data centers strategically positioned for critical applications, constitute vital components of today's technological infrastructure. Traditional data centers serve as centralized hubs supporting services like cloud computing, while edge centers, located nearer to end-users, play a pivotal role in applications such as augmented and virtual reality.

  4. 23. Modeling and Control of VSC-HVDC Links Connected to Weak AC Systems

    Författare :Lidong Zhang; Hans-Peter Nee; Alan Wood; KTH; []
    Nyckelord :Control; modeling; multivariable feedback control; HVDC; power systems; stability; subsynchronous torsional interaction; voltage-source converter; weak ac systems;

    Sammanfattning : For high-voltage direct-current (HVDC) transmission, the strength of the ac system is important for normal operation. An ac system can be considered as weak either because its impedance is high or its inertia is low. LÄS MER

  5. 24. Interaction analysis and control of bioreactors for nitrogen removal

    Författare :Björn Halvarsson; Bengt Carlsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Efficient control of wastewater treatment processes are of great importance. The requirements on the treated water (effluent standards) have to be met at a feasible cost. This motivates the use of advanced control strategies. LÄS MER

  7. 25. On Structure Exploiting Numerical Algorithms for Model Predictive Control

    Författare :Isak Nielsen; Daniel Axehill; Anders Hansson; Pontus Giselsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the most common advanced control strategies used in industry today is Model Predictive Control (MPC), and some reasons for its success are that it can handle multivariable systems and constraints on states and control inputs in a structured way. At each time-step in the MPC control loop the control input is computed by solving a constrained finite-time optimal control (CFTOC) problem on-line. LÄS MER
