CONTROL SYSTEM FOR A VIBRATING STRUCTURE GYROSCOPE |
摘要 |
<p>A vibrating structure gyroscope having a vibrating structure (3) primary drive means (4) and secondary drive means (7) and primary pick-off means (2) an secondary pick-off means (6) is provided with a control system. The control system includes a primary closed control loop (1) for controllably varying the drive signal applied to the primary drive means (4), a secondary closed control loop (5) for controllably varying the drive signal applied to the secondary drive means (7) in order to maintain a null value of the secondary pick-off means (6) and means (30) for actively adjusting the scalefactor in the primary and secondary closed control loops (1, 5). The means (30) includes means (34) for dividing a rate response signal from the loop (5) by a signal indicative of the amplitude of the primary mode vibration. The output form the means (34) is filtered to provide an applied rate output. A variable scalefactor loop (3) uses the output from the means (34) actively to adjust a reference voltage set level of loop (1) to adjust the in loop scalefactor of the system.</p> |
