1. 1. Comparing Multistep Methods Within Parametric Classes to Determine Viability in Solver Applications

   University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Michael Andrew Kraut; [2021]
   Keywords : Ordinary Differential Equations; Initial Value Problems; Linear Multistep Methods; Numerical Analysis; Numerical Solvers; Parametrized; Algorithms; Control Theory; Mathematics and Statistics;

   Abstract : In the 2017 paper by Arévalo and Söderlind, a framework was established for creating linear multistep methods of various classes based on a polynomial formulation which includes variable step size adaptivity. These classes are: k step explicit and implicit methods of order k and k+1 respectively for nonstiff problems (such as Adams methods), and k step implicit methods of order k for stiff problems (such as BDF methods).

3. 2. Map Partition and Loop Closure in a Factor Graph Based SAM System

   University essay from Linköpings universitet/Reglerteknik

   Author : Emil Relfsson; [2020]
   Keywords : SAM; Factor graph; Map partition; Smoothing and Mapping; SLAM;

   Abstract : The graph-based formulation of the navigation problem is establishing itself as one of the standard ways to formulate the navigation problem within the sensor fusion community. It enables a convenient way to access information from previous positions which can be used to enhance the estimate of the current position. READ MORE

4. 3. Automatic Parking and Path Following Control for a Heavy-Duty Vehicle

   University essay from Linköpings universitet/Reglerteknik

   Author : Joakim Mörhed; Filip Östman; [2017]
   Keywords : Control theory; Automatic parking; Autonomous; Parking; Path following; Controller; Heavy-Duty vehicle; Scania; Occupancy grid map; Linear quadratic control; LQ controller; Model predictive control; MPC controller; HDV;

   Abstract : The interest in autonomous vehicles has never been higher and there are several components that need to function for a vehicle to be fully autonomous; one of which is the ability to perform a parking at the end of a mission. The objective of this thesis work is to develop and implement an automatic parking system (APS) for a heavy-duty vehicle (HDV). READ MORE

5. 4. Attitude Navigation using a Sigma-Point Kalman Filter in an Error State Formulation

   University essay from KTH/Rymd- och plasmafysik

   Author : Periklis-Konstantinos Diamantidis; [2017]
   Keywords : unscented Kalman filtering; information ltering; quaternions; attitude navigation; gyroscope modelling; error state formulation; sensor fusion;

   Abstract : Kalman filtering is a well-established method for fusing sensor data in order to accuratelyestimate unknown variables. Recently, the unscented Kalman filter (UKF) has beenused due to its ability to propagate the first and second moments of the probability distribution of an estimated state through a non-linear transformation.

6. 5. Mathematical Modelling of The Global Positioning System Tracking Signals

   University essay from Blekinge Tekniska Högskola/Avdelningen för matematik och naturvetenskap

   Author : Mounchili Mama; [2008]
   Keywords : GPS; GIS; Data Acquisition; Phase-Locked Loop; Z-Transform; Code Tracking;

   Abstract : Recently, there has been increasing interest within the potential user community of Global Positioning System (GPS) for high precision navigation problems such as aircraft non precision approach, river and harbor navigation, real-time or kinematic surveying. In view of more and more GPS applications, the reliability of GPS is at this issue. READ MORE
