Abstract

The invention provides an all-angle control signal detection system of a piezoelectric hemispherical resonator gyroscope. The all-angle control signal detection system comprises the hemispherical resonator gyroscope, two phase-locked loops, a demodulator module, a parameter calculator module, a PI controller module and a modulator module. The X axis and the Y axis of the hemispherical resonator gyroscope are a 0-degree electrode axis and a 45-degree electrode axis respectively. The 0-degree electrode axis and the 45-degree electrode axis are connected with the phase-locked loops respectively. The phase-locked loops are connected with the demodulator module which demodulates same-direction and orthogonal reference signals output by the two phase-locked loops. The parameter calculator module is connected with the demodulator module. The PI controller is connected with a parameter calculator. The modulator is connected with the PI controller and the hemispherical resonator gyroscope. By designing and controlling a closed-loop circuit of the hemispherical resonator gyroscope, all-angle detection and control of the hemispherical resonator gyroscope are achieved.
