  1. 1. Resource-Constrained Embedded Control and Computing Systems

    Författare :Dan Henriksson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

    Sammanfattning : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. LÄS MER

  3. 2. Tools for Autonomous Process Control

    Författare :Anders Wallén; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.

  4. 3. Iterative Learning Control : Analysis, Design, and Experiments

    Författare :Mikael Norrlöf; Svante Gunnarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; Robot programming; Robot modeling;

    Sammanfattning : In many industrial robot applications it is a fact that the robot is programmed to do the same task repeatedly. By observing the control error in the different iterations of the same task it becomes clear that it is actually highly repetitive. LÄS MER

  5. 4. Fixed-Feedback SISO Adaptive Control

    Författare :Magnus Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Two-Degrees-of-Freedom Control; Feedforward Control; Adaptive Control;

    Sammanfattning : Adaptive control is an attractive method to solve control problemssince the tedious task of identifying process behavior to find asuitable design for the controller is taken care of by the adaptivecontroller itself. It may be difficult, however, to guaranteerobustness (in the sense of desired disturbance attenuation andstability margins) for traditional adaptive schemes since theircorresponding loop gain is time varying.

  7. 5. Extremum Seeking Control : Stability, Accuracy, and Applications

    Författare :Khalid Atta; Ying Tan; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In many applications, there is a variable that indicates the overall performance and that must be maximized, such as the output of a hydro power turbine or a mineral processing plant, or that must be minimized, such as CO2 emissions or the consumption of resources. Extremization of this variable (maximization or minimization) through adjusting the influencing manipulated variables is occasionally required without prior knowledge of the optimal values of the manipulated variables or of the optimized variable.
