반구형 공진 자이로스코프의 신호 검출 및 제어 = Signal Detection and Control of Hemispherical Resonator Gyroscopes

다국어 초록 (Multilingual Abstract)

In this paper, signal detection and control circuits for hemispherical resonator gyroscope(HRG) are designed, simulated and tested. HRG is one of the coriolis vibratory gyroscope(CVG) which has very stable quartz hemispherical resonator and shows very precise performance. HRG signals are usually modulated at the several kHz of resonant frequency. So the general control scheme cannot be applied directly because general control schemes mainly focused at low frequency range. Using demodulated and modulated PI control scheme with the signal detection which is presented in this paper, performance of manufactured HRG has tested.
