Robust eigenvalue assignment by periodic feedback

Sauro Longhi and Romolo Zulli


In this paper a robust periodic eigenvalue assignment algorithm is proposed for linear, time-invariant, discrete-time systems. The condition numbers characterizing the eigenstructure of the closed-loop system are assumed as a robustness measure. Alternative robustness measures are also introduced. The proposed periodic eigenvalue assignment algorithm has been tested on many different examples, giving satisfactory results.
