It makes good preparations for designing a controller and forming a control loop.

为进一步设计控制器，形成闭环控制作准备。

The performance of control system will degenerate with elapsed time to a control loop if there is no periodic maintenance.

对于控制回路，如果没有定期的维护，控制系统的性能会随着时间推移而退化。

In the second case, a nonlinear element may be situated anywhere in a control loop while the input of the element is known.

第二种情况是非线性元件在控制系统的任意处而其输入是已知的。
