Abstract
A gyroscope control circuit for a vibratory gyroscope system includes an open-loop RSP control circuit and a closed-loop CSP control circuit. The gyroscope control circuit optionally may include a Q compensation circuit to compensate for variations in gyroscope sensitivity due to variations in resonator signal path Q. The resonator signal path and the Coriolis signal path may have transduction factors that are proportional to each other such that sensitivity of the gyroscope varies directly with resonator signal path quality factor (Q).
