摘要
试验验证了光纤陀螺的死区,分析了电路的交叉耦合是产生死区的主要原因。同时,调制器当2π复位电压不准确或者解调信号存在尖峰脉冲时,阶梯波与方波的数字叠加,也容易出现较大死区。提出了抑制死区的具体措施。
The deadband of FOG is vertified by experiment. It's mainly caused by the electrical crosscoupling in the gyro electronics. Furthermore, when the reset voltage of two π is inaccurate or the transient spikes is existed in modulating signal, the overlap between the ramp wave and square wave may bring the deadband. The paper proposed the way of eliminating the deadband.
