The invention discloses an axisymmetric resonant gyroscope parameter excitation method based on discrete electrodes. The method comprises the following steps: step 1, providing n excitation electrodeswhich are arranged on a hemispherical resonator gyro at intervals, and setting directions to meet the formula; step 2, applying a direct-current bias voltage and an excitation voltage to the excitation electrodes for parameter excitation, the frequency of the excitation voltage being twice of that of a resonator vibration signal, wherein the voltage applied to the ith excitation electrode is Vi =VbiasV0cos2omega lambda t; and step 3, adjusting the frequency of the excitation voltage and the amplitude of the excitation voltage to enable the frequency of the excitation voltage and the frequency of the excitation voltage to reach the minimum voltage and resonance frequency of parameter excitation, and enabling the amplitude of the excitation voltage to be the minimum value of the stable boundary voltage under harmonic oscillator parameter excitation. According to the invention, through the excitation of the discrete electrodes, the place with the maximum amplitude can obtain the maximumenergy supplement, and the energy supplement does not influence the standing wave orientation at the moment, thereby avoiding the binding phenomenon of the standing wave orientation caused by a conventional position excitation mode, and improving the precision and performance of the axisymmetric resonant gyroscope.
