| 摘 要： | 为了获得最佳的驱动效率,采用相位控制技术设计了微陀螺谐振环路,使微陀螺产生驱动模态谐振.为了提高微陀螺的稳定性,设计了ITAE性能指标最优的PID控制器,使微陀螺驱动轴振动幅值保持恒定.闭环驱动电路的测试结果表明,谐振环路振荡频率与驱动模态频率非常接近,采用PID控制器后,在一40℃～80℃范围内,微陀螺驱动轴振动幅值的变化仅为0.1%,振动幅值稳定性有显著改善.

| Abstract: | In order to achieve high excitation efficiency,a resonance loop for microgyroscope is designed based on phase control technology to generate drive mode resonance.In order to improve the stability of microgyroscope,a PID controller with best ITAE criterion is designed to keep the drive oscillation amplitude invariable.A closed-loop drive circuit is fabricated and tested.The results show that the oscillation frequency of the fabricated drive loop is very close to the drive mode frequency.With the adoption of ... |
