    To decrease the influence of resonator eccentricity to output of Hemispherical Resonator Gyroscope (HRG) in force feedback model, three schemes were designed to measure the resonator amplitude. Firstly, based on the dynamic motion equation of resonator in radial direction, the expression of gyros output was established. Then, the amplitude measured by different schemes was inferred in the condition of resonator eccentricity. Based on the amplitude, gyros output corresponding to each measurement scheme was obtained. At last, the output relative error of each scheme was calculated out by simulation. The simulation result showed that the third scheme has the best performance for decreasing the influence of resonator eccentricity to gyros output.
