High accurate double channels rotary transformer is the position detecter of the launcher, feeding back the position information of the closed-loopcontrolsystem.
采用高精度双通道旋转变压器作为发射架的位置检测装置，实现了闭环控制系统中位置信息的反馈。

By theoretical(analysis, ) the closed-loopcontrolsystem is proven to be semiglobally uniformly ultimately bounded, (with) tracking error converging to a residual set.
通过理论分析，证明了闭环系统是半全局一致终结有界的，跟踪误差收敛到一个小的残差集内。

The control scheme and operating principle of a double closed-loop AC/DC power converter system are discussed by using physics.
