Structural Controllability of Discrete-Time Linear Control Systems with Time-Delay: A Delay Node Inserting Approach

الملخص EN

This paper is concerned with the structural controllability analysis for discrete-time linear control systems with time-delay.

By adding virtual delay nodes, the linear systems with time-delay are transformed into corresponding linear systems without time-delay, and the structural controllability of them is equivalent.

That is to say, the time-delay does not affect or change the controllability of the systems.

Several examples are also presented to illustrate the theoretical results.
