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

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

    Abstract : 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. READ MORE

  4. 2. Condition Monitoring of Control Loops

    Author : Alexander Horch; KTH; []
    Keywords : control performance; performance index; detection; dead-time; diagnosis; static friction; disturbances;

    Abstract : The main concern of this work is the development of methodsfor automatic condition monitoring of control loops withapplication to the process industry. By condition monitoringboth detection and diagnosis of malfunctioning control loops isunderstood, using normal operating data and a minimum amount ofprocess knowledge. READ MORE

  5. 3. Efficient Energy Harvesting Interface for Implantable Biosensors

    Author : Janko Katic; Ana Rusu; Saul Rodriguez; Jonny Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Implantable biosensors; thermoelectric energy harvesting; energy harvesting interface; power management; DC-DC converters; dead time losses; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Energy harvesting is identified as a promising alternative solution for powering implantable biosensors. It can completely replace the batteries, which are introducing many limitations, and it enables the development of self-powered implantable biosensors. READ MORE

  6. 4. Feedforward Control in Dynamic Situations

    Author : Björn Johansson; Erik Hollnagel; Berndt Brehmer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human; computer interaction; informatioon policy; organisational control; Computer science; Datavetenskap;

    Abstract : This thesis proposal discusses control of dynamic systems and its relation to time. Although much research has been done concerning control of dynamic systems and decision making, little research exists about the relationship between time and control. Control is defined as the ability to keep a target system/process in a desired state. READ MORE

  7. 5. Determination of actinides using ICP-SFMS

    Author : Ulrika Nygren; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Interest in the determination of the actinides using ICP-MS has steadily increased with the development of systems capable of more sensitive and precise measurements. However, the analysis of less abundant actinides such as Pu and Am is not straightforward due to the need for chemical separation of these elements prior to determination. READ MORE
