PI Controller Design for Time Delay Systems Using an Extension of the Hermite-Biehler Theorem

Abstract EN

We consider stabilizing first-order systems with time delay.

The set of all stabilizing proportional-integral PI controllers are determined using an extension of the Hermite-Biehler theorem.

The time delay is approximated by a second-order Padé approximation.

For uncertain plants, with interval type uncertainty, robust stabilizing PI controllers are determined.
