1. 21. Applications of Integer Quadratic Programming in Control and Communication

   Författare :Daniel Axehill; Anders Hansson; Anders Rantzer; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Model Predictive Control; CDMA; Quadratic Programming; Mixed Integer Quadratic Programming; Dual active set methods; Riccati recursion; Branch and bound; Automatic control; Reglerteknik;

   Sammanfattning : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control principles is the discrete-time method Model Predictive Control (MPC). LÄS MER

3. 22. Towards Active Car Body Suspension in Railway Vehicles

   Författare :Jessica Fagerlund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

   Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER

4. 23. PID Control, Design, Extension, Application

   Författare :Helene Panagopoulos; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; PID control. Design. Optimization. Load disturbance rejection. Measurement noise filtering. Set point response.

Pulp and paper.; robotics; Automation; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. LÄS MER

5. 24. Dryer Section Control in Paper Machines During Web Breaks

   Författare :Jenny Ekvall; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dryer Section; Web breaks; Paper machine; steam pressure control; Physical modeling; Automatic control; Reglerteknik; Dryer section; paper machine; physical modeling; steam pressure control; web breaks;

   Sammanfattning : Web breaks in the dryer section of a paper machine cause loss of production and quality problems. After a web break, the steam pressure in the cylinders must be reduced to avoid overheating. LÄS MER

7. 25. On Supervisor Synthesis via Active Automata Learning

   Författare :Ashfaq Hussain Farooqui; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervisory control theory; Finite-state machines; Active learning; Model learning; Automata learning; Discrete-event systems;

   Sammanfattning : Our society's reliance on computer-controlled systems is rapidly growing. Such systems are found in various devices, ranging from simple light switches to safety-critical systems like autonomous vehicles. In the context of safety-critical systems, safety and correctness are of utmost importance. LÄS MER
