Hélant Muller, Diego (author)
This thesis report has explored the complex field of satellite formation flying, focusing on Guidance, Navigation and Control (GNC) strategies for maintaining formations of multiple satellites. The research has been guided by a series of research questions aimed at improving the understanding and implementation of GNC systems for satellite...

Abstract—Ultra-wideband (UWB) ranging is a very suitable method for indoor localisation of unmanned aerial vehicles (UAVs). Current solutions of UWB ranging however either focus on achieving a high accuracy or focus on scalability. In this research a positioning algorithm for UAVs is presented that combines high accuracy performance with a high...

Pose estimation provides accurate position and orientation information of the intelligent agents in real time. The accuracy of the estimation directly affects the performance of sequential tasks such as mapping, motion planning, and control. EKF (Extended Kalman Filter) is a standard theory for nonlinear pose estimation by modeling state...

Inertial measurement units (IMUs) are getting more and more incorporated into our lives due to their improving accuracy, lower cost and smaller sizes. Applications for inertial-based orientation estimation can already be found in the field of computer vision, aerospace engineering, robotics, navigation, biomechanics, health monitoring and sports...

In this paper, we propose a method for continuous monitoring of vital signs-in particular, respiration frequency-with a commercial mm-wave radar. The nearly constant frequency (NCF) model is adopted to represent chest displacement due to respiration and simulate radar response. Based on this model, an extended Kalman filter (EKF) based...

Su, Guigeng (author)
With an LFMCW automotive radar operating at its center frequency of 77GHz, the sequential estimation of frequency and amplitude for vital signs, namely, respiration and heartbeat, are considered. The radar response of vital signs is described and analyzed. With extraction of the phase history, extended Kalman filter and particle filter are...

A novel wingman-based estimation and guidance concept is proposed for a sensorless pursuer. The pursuer is guided towards a maneuvering aerial target using proportional navigation (PN) guidance law. The wingman is assumed to acquire bearings-only measurements of the target and to accurately track the wingman-pursuer relative position. The...

Facchinelli, Michele (author)
The amount of propellant required to perform deep-space maneuvers usually consists of a large percentage of the total spacecraft mass. In the early '90s, a new technique was experimented at the end of the Magellan mission, which employed the atmosphere of Mars itself, to reduce the eccentricity of the orbit over a long period of time. Said...

Determining the magnitude of particular fault signature components (FSCs) generated by wind turbine (WT) faults from current signals has been used as an effective way to detect early abnormalities. However, the WT current signals are time varying due to the constantly varying generator speed. The WT frequently operates with the generator close...

High-speed autonomous flight of Micro Air Vehicles has gained much attention in recent years. However, flight in complex GPS-denied environments still poses a serious challenge. One scenario which contains these elements is drone racing, where pilots have to fly complex tracks at high speed, often in an indoor environment. In this work we...

Rijnsdorp, J. (author)
Re-entry is a term that is applied when one would like to transport some (human) payload from an orbit around a certain body towards the surface of that body. With an entry velocity of multiple kilometers per second, having the vehicle carrying this payload not smashed into pieces at the end of flight is one of the key points of re-entry. Using...

Pietaloka, D. (author)
The purpose of this research is mainly to develop a distributed dynamic state estimation with PMU and SCADA as a response of the challenges in state estimation problems (accuracy, computational time, the use of new technology along with the ability to keep the existing traditional measurement). With the implementation of statistical signal...

Different nonlinear observers are compared throughout this work where they are part of an NMPC framework used to control a fed-batch crystallization process . We study which observer-optimizer pair offers the best control performance while maintaining adequate computational burden so that a posterior real-time implementation is feasible. At the...
