Statecontrollability of a linear system is an important performance of a system and a basic and important concept of the linear system theory.
线性系统的状态可控性是系统的一种重要的特性，是线性系统理论中一个基本而重要的概念。

If a system can transfer toward arbitrary desired state from the arbitrary initial state within a finite time interval under the governing of the control action, then it has controllability.
系统在控制作用支配下能够在有限时间间隔内从任意初始状态向任意希望状态转移，则其具有能控性。

Polymer process control is limited by a lack of observability and controllability of the state of the polymer melt.
