On the test bed studying the close loop control, applying performance test of some cycle , explain the actual control flow chart at the same time.

并在该构建的平台上进行了闭环自动控制，来进行某一循环工况的性能试验，同时给出其实际的控制流程。

Combining the observer and the control law leads to control without velocity measurements. The close loop system is proved to be asymptotically stable.

观测器与控制律的结合实现了无速度测量的控制，闭环系统被证明是渐近稳定的。
