Ayazi, A Polysilicon micro hemispherical resonating gyroscope. The efficiency of the energy transmission is increased, and the sensitivity of the gyroscope is enhanced too. The different computed AC voltages are applied to the different driving electrodes, which causing the standing wave to rotate, and a new electrostatic control algorithm is presented, which based on the vector composition and decomposition method to control the equivalent drive force in order to track the phase of the standing wave. In the paper, a different method to sustain the vibration energy is presented and implemented. The traditional control algorithm is based on average methods which usually used for the WA mode. However, due to the manufacture error of the resonator, besides of the angle precession according to the Coriolis’ Effect, the standing wave is shift around the hemispheric shell, which will arouse the performance reduction. The excitation axes are fixed by the driving electrodes and the fixed voltage is placed on the driving electrodes to maintain the fixed vibration energy of the resonator. In the case of the WA mode, the standing wave of the resonator is free to rotation around the body of the shell. Compared with the FTR mode, the WA mode has high dynamic range, fast response and none of the rate integrated error. The HRG has been mechanized to operate in two operating modes, the FTR mode and the WA mode. Due to the simple structure and fixed mechanical components, the HRG has the characteristics of small size, high reliability and long life-time. The HRG is an important kind of the inertial sensor based on the Coriolis’ Effect. ![]()
