A resonant drive control system is designed. And an automatic gain control (AGC) loop is introduced to keep the vibrating amplitude of dive tines invariable. It will effectively improve the linearity and robustness of the gyro.

• 设计了微陀螺谐振驱动控制系统,引入了自动增益控制环节,使驱动音叉振动幅值保持恒定,提高了微陀螺的测量线性度,增强了微陀螺的鲁棒性,并且详细介绍了驱动控制电路的实现方法。
