4. 2. Relative Information Based Distributed Control for Intrinsic Formations of Reduced Attitudes

   Author : Silun Zhang; Xiaoming Hu; Junfeng Wu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Attitude control; distributed control; formation control; nonlinear systems; Mathematics; Matematik;

   Abstract : This dissertation concerns the formation problems for multiple reduced attitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. In contrast to most existing methodologies on formation control, the proposed method does not need to contain any formation errors in the protocol. READ MORE

5. 3. Nonlinear Control of Unmanned Aerial Vehicles : Systems With an Attitude

   Author : Marcus Greiff; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Control; Lyapunov Methods; Aerospace; Aerial Vehicles; Output Feedback; Control Theory;

   Abstract : This thesis deals with the general problem of controlling rigid-body systems through space, with a special focus on unmanned aerial vehicles (UAVs). Several promising UAV control algorithms have been developed over the past decades, enabling truly astounding feats of agility when combined with modern sensing technologies. READ MORE

6. 4. Rigid-Body Attitude Control and Related Topics

   Author : Johan Markdahl; Xiaoming Hu; Bijoy Ghosh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

   Abstract : This dissertation explores aspects of control in rigid-body and robotic systems. The first and second paper analyze the attitude stabilization problem and its generalization to n-dimensional rigid bodies. READ MORE

7. 5. Partitioning and Control for Dynamical Systems Evolving on Manifolds

   Author : Xiao Tan; Dimos V. Dimarogonas; James D. Biggs; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioning and control; Transition system; Geometric control; Barrier functions; Electrical Engineering; Elektro- och systemteknik;

   Abstract : With the development and integration of cyber-physical and safety-critical systems, control systems are expected to achieve tasks that include logic rules, receptive decision-making, safety constraints, and so forth. For example, in a persistent surveillance application, an unmanned aerial vehicle might be required to "take photos of areas A and B infinitely often, always avoid unsafe region C, and return to the charging point when the battery level goes low.
