AI Technical Summary
When a hemispherical resonator gyroscope is sampled by X/Y electrodes in a time-division multiplexing manner, the sampling signal from the X/Y electrodes has a standing wave azimuth angle error. Traditional demodulation methods introduce demodulation errors, which affect the gyroscope control accuracy.
A high-precision demodulation method for hemispherical resonant gyroscopes is designed. The demodulation algorithm is designed based on the error characteristics of the X/Y channel time-division sampling signals. The average of the control parameters of the X-channel signal at the previous moment and the current moment is used as the control parameters of the Y-channel sampling moment to suppress demodulation error.
High-precision demodulation of hemispherical resonant gyroscope signals was achieved, improving the control accuracy of the gyroscope, eliminating demodulation errors, and meeting the high-precision requirements of the new generation of weapons and equipment.
