1. 1. Coordinate­Free Spacecraft Formation Control with Global Shape Convergence under Vision­Based Sensing

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Omid Mirzaeedodangeh; [2023]
   Keywords : Bispherical Coordinates; 3D Formation Control; Spacecraft Formation Flying; Multiagent Systems; Prescribed Performance Control; Vision-Based Sensing; Bisfäriska Koordinater; 3D Formationskontroll; Rymdfarkostformationsflygning; Multiagentsystem; Föreskriven Prestandakontroll; Synbaserad Avkänning;

   Abstract : Formation control in multi-agent systems represents a groundbreaking intersection of various research fields with lots of emerging applications in various technologies. The realm of space exploration also can benefit significantly from formation control, facilitating a wide range of functions from astronomical observations, and climate monitoring to enhancing telecommunications, and on-orbit servicing and assembly.

3. 2. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

   University essay from KTH/Bro- och stålbyggnad

   Author : Sicong Wei; [2020]
   Keywords : high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

   Abstract : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. READ MORE

4. 3. Optimal Control Model for an Autonomous Underwater Vehicle

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gustav Holm; [2020]
   Keywords : ;

   Abstract : The main goal with this thesis was to develop an optimal control model for anautonomous underwater vehicle (AUV) and evaluate whether reference trackingusing Model Predictive Control (MPC) based on a linear dynamics modeldescribing all six degrees of freedom (DOF) is a suitable method for waypointnavigation. MPC is an advanced receding horizon optimal control method capableof including constraints in the optimization. READ MORE

5. 4. Model Based HandlingAnalyses

   University essay from KTH/Fordonsdynamik

   Author : Paolo Perinciolo; Eshwar Sondhi; [2018]
   Keywords : ;

   Abstract : The thesis consists of building vehicle models for lateral dynamics that provide accurate results, while being simple enough to highlight clear relationships between vehicle properties and handling behaviours. The approach that characterizes the present work is built on the foundations provided by the bicycle, or single-track, model (STM). READ MORE

6. 5. Real Time Reachability Analysis for Marine Vessels

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Sudakshin Ganesan; [2018]
   Keywords : Reachable set; Safety Verification; Marine dynamics; Machine Learning; Optimal control; Säkerhetsverifiering; nåbarhetsanalys; fartyg dynamisk;

   Abstract : Safety verification of continuous dynamical systems require the computationof the reachable set. The reachable set comprises those states the systemcan reach at a specific point in time. READ MORE
