1. 26. Estimation-based iterative learning control

   Författare :Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Jian-Xin Xu; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Iterative learning control; estimation; industrial robotics; performance; Automatic control; Reglerteknik;

   Sammanfattning : In many  applications industrial robots perform the same motion  repeatedly. One way of compensating the repetitive part of the error  is by using iterative learning control (ILC). The ILC algorithm  makes use of the measured errors and iteratively calculates a  correction signal that is applied to the system. LÄS MER

3. 27. Predictive control for autonomous driving : With experimental evaluation on a heavy-duty construction truck

   Författare :Pedro Lima; Bo Wahlberg; Jonas Mårtensson; Alberto Bemporad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; automatic control; heavy-duty vehicles; mining; trucks; clothoids; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Autonomous vehicles is a rapidly expanding field, and promise to play an important role in society. In more isolated environments, vehicle automation can bring significant efficiency and production benefits and it eliminates repetitive jobs that can lead to inattention and accidents. LÄS MER

4. 28. Compensating for Unreliable Communication Links in Networked Control Systems

   Författare :Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

   Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER

5. 29. Coordination, Consensus and Communication in Multi-robot Control Systems

   Författare :Alberto Speranzon; Karl Henrik Johansson; George J. Pappas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot Coordination; Intelligent Control; Control under Communication Constraints; Automatic control; Reglerteknik;

   Sammanfattning : Analysis, design and implementation of cooperative control strategies for multi-robot systems under communication constraints is the topic of this thesis. Motivated by a rapidly growing number of applications with networked robots and other vehicles, fundamental limits on the achievable collaborative behavior are studied for large teams of autonomous agents.

7. 30. 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
