| 摘要 |
A digital control system for a vibrating structure gyroscope having a vibrating structure (3), at least a primary drive means (4) for putting and maintaining the vibrating structure (3) in vibratory resonance, and at least a primary pickoff means (2) for detecting vibration of the vibrating structure (3), includes a digital processing unit (22) for receiving output signals from the pickoff means (2) for processing the received signals and for passing them to the primary drive means (4) via digital to analogue converters (20). The system includes means for 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 sample means sampling intervals.
