   Författare :Johan Andersson; Sören Andersson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis focuses on how to improve design and development of complex engineering systems by employing simulation and optimization techniques. Within the thesis, methods are developed and applied to systems that combine mechanical, hydraulical and electrical subsystems, so-called multi-domain systems. LÄS MER

5. 34. On design of low order H-infinity controllers

   Författare :Daniel Ankelhed; Anders Hansson; Anders Helmersson; Jakob Stoustrup; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity synthesis; linear systems; linear matrix inequalities; rank constraints; optimization; rational constraints; interior point methods; Automatic control; Reglerteknik;

   Sammanfattning : When designing controllers with robust performance and stabilization requirements, H-infinity synthesis is a common tool to use. These controllers are often obtained by solving mathematical optimization problems. The controllers that result from these algorithms are typically of very high order, which complicates implementation. LÄS MER

7. 35. Competitive Learning in Robust Communication

   Författare :Petter Knagenhjelm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A modern communication system should be accurate, reliable, robust and make efficient use of the available channel. Vector quantization is beginning to prove its effectiveness for source coding in applications such as cellular mobile telephony. The design of vector quantizers is typically done by clustering methods. LÄS MER
