Realtime state estimation for contact manipulation
In this thesis, we develop a real-time state estimation system to recover the pose and contact state of an object relative to its environment. The capability to make such estimations is important for a controller to adequately react to uncertainties in a manipulation task. We propose a framework …

Robust state estimation in power systems
The application of robust estimation methods to the power system state estimation problem was investigated. Techniques using both nonlinear and combinatorial optimization were considered, based on the requirements that the method developed should be statistically robust, and fast enough to be used …

Visual-Inertial State Estimation With Information Deficiency
State estimation is an essential part of intelligent navigation and mapping systems where tracking the location of a smartphone, car, robot, or a human-worn device is required. For autonomous systems such as micro aerial vehicles and self-driving cars, it is a prerequisite for control and motion …

State Estimation for Distributed and Hybrid Systems
This thesis deals with two aspects of recursive state estimation: distributed estimation and estimation for hybrid systems. In the first part, an approximate distributed Kalman filter is developed. Nodes update their state estimates by linearly combining local measurements and estimates from their …

Improved State Estimation for Miniature Air Vehicles
… in order for the UAV to accurately determine its state and thereby allow the use of feedback in controlling the aircraft automatically. This work presents a three-stage state-estimation scheme for the class of UAV's know as Miniature Air Vehicles (MAV's). The first stage estimates pitch and roll, …
