  2. 11. Integrated Control and Real-Time Scheduling

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

    Abstract : 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. READ MORE

  4. 12. Active Control of Propeller-Induced Noise in Aircraft : Algorithms & Methods

    Author : Sven Johansson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active control of sound; active noise control; anc; actuator individual normalized filtered-x lms; filtered-x lms algorithm; newton algorithm; complex lms; multireference algorithm; leaky lms; control effort weighting; feedforward control; feedback contro;

    Abstract : In the last decade acoustic noise has become more and more regarded as a problem. In cars, boats, trains and aircraft, low-frequency noise reduces comfort. Lightweight materials and more powerful engines are used in high-speed vehicles, resulting in a general increase in interior noise levels. READ MORE

  5. 13. 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

  6. 14. Wireless Sensor Network Scheduling and Event-based Control for Industrial Processes

    Author : Takuya Iwaki; Karl H. Johansson; Vijay Gupta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; Wireless sensor and actuator network; Event-based control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Control over wireless sensor and actuator networks is of growing interest in process industry since it enables flexible design, deployment, operation, and maintenance. An important problem in industrial wireless control is how to limit the amount of information that needs to be exchanged over the network. READ MORE

  7. 15. Active Noise Control in Aircraft : Algorithms and Applications

    Author : Sven Johansson; []
