In this paper,a modification to the eigenmode operation of resonant gyroscopes is *** multi-coefficient eigenmode operation can improve cross-mode isolation due to electrode misalignments and imperfections,which is one of the causes of residual quadrature errors in conventional eigenmode operations.A 1400µm annulus aluminum nitride(AlN)on a silicon bulk acoustic wave(BAW)resonator with gyroscopic in-plane bending modes at 2.98 MHz achieves a nearly 60 dB cross-mode isolation when operated as a gyroscope using a multi-coefficient eigenmode *** as-born frequency mismatches in multiple devices are compensated by physical laser *** demonstrated AlN piezoelectric BAW gyroscope shows a large open-loop bandwidth of 150 Hz and a high scale factor of 9.5 nA/°/s on a test board with a vacuum *** measured angle random walk is 0.145°/√h,and the bias instability is 8.6°/h,showing significant improvement compared to the previous eigenmode AlN BAW *** results from this paper prove that with multi-coefficient eigenmode operations,piezoelectric AlN BAW gyroscopes can achieve a noise performance comparable to that of their capacitive counterpart while having the unique advantage of a large open-loop bandwidth and not requiring large DC polarization voltages.
The actor-critic reinforcement learning (RL) is widely used in various robotic control tasks. By viewing the actor-critic RL from the perspective of variational inference (VI), the policy network is trained to obtain ...
