Gyroscope dynamic motor amplitude compensation for enhanced rate estimation during startup |
摘要 |
A system for gyroscope dynamic motor amplitude compensation during startup comprises various program modules, including an a-priori motor amplitude module configured to generate an a-priori motor amplitude signal based on a model of gyroscope motor amplitude growth during startup; a steady state scale factor module configured to generate a steady state scale factor signal; and a dynamic motor amplitude compensation module configured to receive the a-priori motor amplitude signal, and the steady state scale factor signal. During startup, rate motion is sensed by the gyroscope and a sensed rate signal is output by the gyroscope. The dynamic motor amplitude compensation module receives a measured motor amplitude signal from the gyroscope, the a-priori motor amplitude signal, or a combination thereof, and outputs a time varying scale factor that is applied to the sensed rate signal to produce an accurate sensed rate from the gyroscope during the startup phase. |
