This example shows how the Control System Toolbox™ lets you represent, manipulate, and analyze any LTI model with a finite number of delays.
模型时滞
- 线性系统中的时滞
在动态系统模型中表示输入和输出延迟、传输延迟或内部延迟。 - Closing Feedback Loops with Time Delays
Interconnecting models that have time delays can give rise to internal delays. - Internal Delays
