1. 1. Fuzzy Control for an Unmanned Helicopter

   Författare :Bourhane Kadmiry; Dimiter Driankov; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Helicopter; Robust control; Fuzzy gain scheduling; Gradient descent method; Computer science; Datavetenskap;

   Sammanfattning : The overall objective of the Wallenberg Laboratory for Information Technology and Autonomous Systems (WITAS) at Linköping University is the development of an intelligent command and control system, containing vision sensors, which supports the operation of a unmanned air vehicle (UAV) in both semi- and full-autonomy modes. One of the UAV platforms of choice is the APID-MK3 unmanned helicopter, by Scandicraft Systems AB. LÄS MER

3. 2. Modelling and Validation of Industrial Measurement Systems - Aspects of Quality and Human Factors

   Författare :Jenny Wirandi; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Analysis; Quality Index; Instrumentation technology; Mät- och instrumenteringsteknik; Traceability; Fuzzy Variable; Pulp Quality; Industrial Measurement; Human Factor; GUM; Calibration; Fibre Measurement; Measurement Science;

   Sammanfattning : Although there is a fairly large number of books and articles concerning the validation of technical measurement systems, there are only a few which take into account the whole measurement system consisting of both technical and non-technical aspects. A measurement system comprises both the measurement process and the human being who conducts the measurement. LÄS MER

   Sammanfattning : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. LÄS MER

5. 4. On modeling and control of complex dynamic systems

   Författare :Limei Ding; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : Nonlinear complex multi-input multi-output process is very troublesome to control. It is usually also ill-modeled. The problem of such process both in control and modeling requires a comprehensive utilization of various techniques. The thesis presents the methods for the modeling and control of complex systems.
