  1. 21. Dead-Time Compensation and Performance Monitoring in Process Control

    Författare :Ari Ingimundarson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Sammanfattning : The thesis contains two parts, dead-time compensation and performance monitoring. The first part on dead-time compensation is about robust tuning procedures for dead-time compensating controllers (DTC). Both stable and integrating processes are considered. LÄS MER

  3. 22. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors

    Författare :Stéphane Velut; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; Large scale fermentations; Extremum control; Feeding strategy; Probing control; Fed-batch bioreactors; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. LÄS MER

  4. 23. Relay Feedback and Multivariable Control

    Författare :Karl Henrik Johansson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Frequency methods; Process control; Sequential control; Automatic tuning; Control education; Laboratory process; Performance limitations; Decentralized control; Multivariable zero; Multivariable systems; Hybrid control; Nonlinear dynamics; Limit cycles; Oscillations; Relay feedback; Sliding modes; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. LÄS MER

  5. 24. Integrated Control and Real-Time Scheduling

    Författare :Anton Cervin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Sammanfattning : The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. LÄS MER

  7. 25. Flexible Embedded Control Systems : Design and Implementation

    Författare :Johan Eker; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. LÄS MER
