loop-gain error

By introducing integral variable structure and high gain observer, the closed-loop control systems is shown to be globally stable in terms of Lyapunov theory, with tracking error converging to zero.

通过引入积分型变结构切换函数及高增益误差观测器，基于李雅普·诺夫稳定性理论，证明了闭环系统是全局稳定的，输出跟踪误差都收敛到零。

The effects of the square wave cycle, phase, duty cycle and the fiber coil group delay and amplifier gain bandwidth on the bias error of closed-loop FOG were analyzed by simulating and testing.

通过仿真和测试分析了调制方波的周期、相位、占空比、光纤环的群延时以及放大电路的增益带宽对陀螺输出偏置的影响。
