Robust Stability in Discrete Control Systems via Linear Controllers with Single and Delayed Time

الملخص EN

In this work, a discrete feedback of single and a delayed time is introduced in a LTI control discrete system, yielding a monoparametric family of LTI systems.

A polynomial approach technique to compute the maximal robust stability interval of the monoparametric system with single and delayed time controller is developed by using the zero exclusion principle and the boundary crossing theorem.

Illustrative examples are given to show the technique.
