7. 5. On robust and optimal control : with real time aspects

   Författare :Torbjörn Norlander; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : This thesis deals with several issues in realistic design of control systems, both from a practical and a theoretical point of view. This is done in three papers which are preceded by an introduction and a short discussion on future research on time-varying delays. The first paper discusses the importance of reliable sensors in control systems. LÄS MER
