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.
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.
