1. 1. Backstepping and control allocation with applications to flight control

   Författare :Ola Härkegård; Torkel Glad; Marc Bodson; Linköpings universitet; []
   Nyckelord :backstepping; control allocation; flight control; control theory; nonlinear control; reglerteknik; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In this thesis we study a number of nonlinear control problems motivated by their appearance in flight control. The results are presented in a general framework and can also be applied to other areas. The two main topics are backstepping and control allocation. LÄS MER

3. 2. Model Predictive Control in Flight Control Design : Stability and Reference Tracking

   Författare :Daniel Simon; Johan Löfberg; Sébastien Gros; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control;

   Sammanfattning : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. LÄS MER

4. 3. Flight Control Design Using Backstepping

   Författare :Ola Härkegård; Torkel Glad; Karin Ståhl Gunnarsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aircraft flight control design is traditionally based on linear control theory, due to the existing wealth of tools for linear design and analysis. However, in order to achieve tactical advantages, modern fighter aircraft strive towards performing maneuvers outside the region where the dynamics of flight are linear, and the need for nonlinear tools arises.

5. 4. Identification and Control of Systems Subject to Abrupt Changes

   Författare :Mille Millnert; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive identification; adaptive control; jumping parameters; Markov regime; time varying parameters;

   Sammanfattning : Many different recursive identification methods for time varying systems have been suggested in the literature. An assumption that the variations in the system parameters are slow is common for almost all the methods. LÄS MER

7. 5. On Communication and Flocking in Multi-Robot Systems

   Författare :Magnus Lindhé; Karl Henrik Johansson; Magnus Egerstedt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; robotics; Automatic control; Reglerteknik;

   Sammanfattning : Coordination of multi-robot systems to improve communication and achieve flocking is the topic of this thesis. Methods are proposed for mobile autonomous robots to follow trajectories in a way that improves communications with a base station. Further, a decentralized algorithm is presented that yields flocking with obstacle avoidance. LÄS MER
