再应用工程设计法设计出调节器，使系统满足静态和动态性能指标。

The engineering design method is applied to elect adjuster expediently, thus the system will fill the static and dynamic capability indexes.

本文设计了一个基于滑模变结构控制的速度调节器，使得系统具有更好的鲁棒性和动、静态性能。

So the author designed a speed regulator based on sliding-mode control theory, which make the system has strong robustness to the parameters, excellent dynamic and steady-state performance.
