1. 16. Trajectory and Pulse Optimization for Active Towed Array Sonar using MPC and Information Measures

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Fabian Ekdahl Filipsson; [2020]
   Keywords : Active Towed Array Sonar; ATAS; Extended Kalman filter; EKF; Unscented Kalman filter; UKF; Information measures; Model predictive control; MPC; Signal processing; Sensor management; Pulse forms; Route planning; Trace; Determinant; Frobenius norm;

   Abstract : In underwater tracking and surveillance, the active towed array sonar presents a way of discovering and tracking adversarial submerged targets that try to stay hidden. The configuration consist of listening and emitting hydrophones towed behind a ship. Moreover, it has inherent limitations, and the characteristics of sound in the ocean are complex. READ MORE

3. 17. Conceptual development of brake friction estimation strategies

   University essay from KTH/Fordonsdynamik

   Author : Kamesh Thiyagarajan; [2020]
   Keywords : Brake friction estimation; Brake friction coefficient; State Estimation; Unscented Kalman Filter; UKF; Moving Horizon Estimation; MHE; Skattning av bromsfriktion; bromsfrikltionskoefficient; skattning; Uncented Kalman Filter; UKF; Moving Horizon Estimation; MHE;

   Abstract : The thesis work investigates brake friction estimation strategies. The friction between the brake disc and brake pads is not constant during the braking application and contributes to the amount of brake torque achieved at the wheels. READ MORE

4. 18. The Effect of Simulink Block Kalman Filters in a CubeSat ADCS

   University essay from KTH/Rymdteknik

   Author : Jesper Larsson; [2020]
   Keywords : ADCS; Kalman Filter; Simulink; Simulation; Block; EKF; UKF; ADCS; Kalmanfilter; Simulink; Simulering; Block; EKF; UKF;

   Abstract : The purpose of this paper was to implement Kalman filtering in the form of pre-existing Simulink blocks into a CubeSat attitude determination and control system simulation and to evaluate their performance. In recent versions of Simulink, the block library has been expanded, providing a new level of abstraction for simulation engineers. READ MORE

5. 19. GPS-oscillation-robust Localization and Visionaided Odometry Estimation

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : HONGYI CHEN; [2019]
   Keywords : Adaptive Extended Kalman Filter; Localization; Stereo visual odometry; GPS outage; Adaptivt förlängt Kalmanfilter; lokalisering; stereovisuell odometri; GPS avbrott;

   Abstract : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. READ MORE

6. 20. Estimating Position and Velocity of Traffic Participants Using Non-Causal Offline Algorithms

   University essay from Linköpings universitet/Reglerteknik

   Author : Casper Johansson; [2019]
   Keywords : Tracking; UKF; RTS; Non-causal; Vehicle tracking; Estimation;

   Abstract : In this thesis several non-causal offline algorithms are developed and evaluated for a vision system used for pedestrian and vehicle traffic. The reason was to investigate if the performance increase of non-causal offline algorithms alone is enough to evaluate the performance of vision system. READ MORE
