Abstract

Gyroscopes have long been used for measuring an object’s angular orientation. Methods range from mechanical spinning disks to oscillating spring-mass systems. However, previous gyroscopes can suffer from high maintenance or fragility. A recently invented novel gyroscope aims to curb these restrictions through the use of ferrofluid.

This thesis proposes a new method of modeling and measuring the signals from the novel gyroscopic device. Rather than simply measuring the device’s average current consumption via slow RMS measurements, an attempt was made to model the voltage amplitude at any time. This allows a faster examination of both the changing magnitude and phase of the AC signal. This changing phase is the key to determining the direction of rotation of the device. Simulation results indicate that the phase difference between the device under rotation and the device at steady-state are very low and may not be detectable with a large noise-floor. Increasing the particle size may improve results.
