Dynamic Experiment Modeling of Hemispherical Resonator Gyro

The ideal dynamic model of hemispherical resonator gyro(HRG) working on the force feedback model is built based on analyzing the operational principle and on introducing the constituent of HRG for building the model of HRG.The dynamic experiment modeling method of HRG is put forward by using the experimental data curve fitting degree as the target to solving the problem of model incongruous between theory and practice.And the experiment proves that the method can be used to building the HRG dynamic model and it can ensure the precision of model.
