Abstract
A digital control system for a vibrating structure gyroscope having a vibrating structure (3), at least a primary drive (4) for putting and maintaining the vibrating structure (3) in vibratory resonance, and at least a primary pickoff (2) for detecting vibration of the vibrating structure (3), includes a digital processing unit (22) for receiving output signals from the pickoff (2) for processing the received signals and for passing them to the primary drive (4) via digital to analogue converters (20). The system includes sampling at selected intervals of time the output signals before passage to the digital processing unit (22) and a variable frequency oscillator (23) connected to and under the control of the digital processing unit (22) for controlling the sampling intervals.
