The fuzzy adaptive controller designed based on this method can guarantees that the closed-loop system is globally stable and the tracking error converges to a neighborhood of zero.

在此基础上设计的模糊自适应控制器能够保证整个闭环系统稳定且跟踪误差收敛到零的一个邻域内。

Secondly, the DC voltage loop and inner current closed-loop control method, both to ensure zero static error of the inverter output, but also to ensure that the inverter output waveform.

其次，本文采用直流电压外环、电流内环的双闭环控制方法，既保证了逆变器输出的静态误差为零，又保证了逆变器良好的输出波形。

Electrooptic phase modulator is critical part in digital closed-loop FOG system, the function of which is to create bias phase, so that to make FOG working around zero point.

电光相位调制器是数字闭环光纤陀螺系统中的关键部件，主要用于产生偏置相移，使整个闭环系统始终工作在零点附近。
