In this report the phenomenon of cross-coupling drift (both S-IA and S-OA) due to vehicular angular movements is investigated. In a hardware test set-up, using an experimental Single Axis Platform composed of surplus parts from the former Eldo-A program, the theoretical result as well as a proposed method of compensation is verified.

Rate gyroscope biases play an important role in flight tests requiring flight path reconstruction, a method of ten used in aircraft parameter estimation. The biases can drift wi th time, be affected by system power up and, ideally, should be calibrated before each flight to maintain optimum performance. This report details a numerical method to...

New emerging sensing applications demand novel sensors in micro-/nano-scale to enable integration and embedding into higher level structures or systems. Downsizing the structure will usually decrease the sensitivity of the sensors, since the sensitivity is a function of geometrical parameters, e.g. mass in the case of inertial sensing, and...

In this thesis , a simulation model of a MEMS gyroscope is presented. The model enables mode matching and analysis of the dynamic behavior of a gyroscope. Furthermore, the model allows the optimization the design parameters of the gyroscope. The simulated gyroscope operates at a frequency of 52MHz with amplitudes of 10nm and quality factor of 50...

Background: Few studies have investigated the use of a 3-dimensional gyroscope for measuring the range of motion (ROM) in the impaired shoulder. Reproducibility of digital inclinometer and visual estimation is poor. This study aims to investigate the reproducibility of a tri axial gyroscope in measurement of anteflexion, abduction and related...

Creating an autonomous flying vehicle the size of a honeybee presents a number of technical challenges because of its small scale. As vehicle wingspan diminishes, angular acceleration rates increase, necessitating sensing and control systems with high bandwidth. Hovering demonstrations have so far required feedback from highspeed motion capture...

A minimalistic robotic device for aiding persons with degraded balancing ability was recently proposed, employing a number of single-gimbal control moment gyroscopes (CMGs) mounted to a backpack-like orthopedic corset. Once a fall is detected, the device must track a predefined moment profile to bring the subject upright or else slow the fall...

Gyroscopic actuation is appealing for wearable applications due to its ability to impart free moments on a body without exoskeletal structures on the joints.We recently proposed an unobtrusive balancing aid consisting of multiple parallelmounted control moment gyroscopes (CMGs) contained within a backpack-like orthopedic corset. Using...

Future space platforms, such as next-generation Earth imaging and missile-tracking satellites, require rapid rotational maneuverability. Currently, most European satellites use reaction wheels as momentum exchange device for their Attitude Control System. However, reaction wheels do not produce enough torque to meet the high slew rate...

Spacecraft attitude refers to the orientation of the spacecraft body axes with respect to the inertial reference frame. Attitude determination and control is the estimation of the current orientation of a satellite and controlling or changing it on demand to reach a desired orientation. The SPS-2 Attitude Control System consists of four modes:...

This paper describes a method to measure the rocking motion of lab-scale armour units. Sensors as found in mobile phones are used. These sensors, data-storage and battery are all embedded in the model units, such that they can be applied without wires attached to them. The technique is applied to double-layer units in order to compare the...

The oceans, which cover nearly 70% of the earth’s surface, can be considered as an inexhaustible energy source for renewable electricity due to its size and predictability. One way to capture ocean energy is by harnessing the energy produced by waves at sea, by means of devices called wave energy converters (WECs).<br/><br/>Delft University of...

Oceans account for 71 percent of the earth’s surface, marine resources and energy are abundant. Therefore, making full use of marine energy is a good choice for humans to solve the energy crisis. One way to capture ocean energy is converting wave energy to electrical energy, by means of devices called wave energy converters (WECs). This project...
