Abstract :
In this paper, the regional pole placement is studied. An analysis of robustness with respect to unstructured uncertainty, being 2-norm bounded, for linear systems is discussed. A bound on the maximum allowable perturbation is proposed. Moreover, a useful parameterization of such bound, based on the structure of the gain matrix and on a novel formula for computing the eigenvectors of any real matrix, is presented. Finally, the problem is formalized as an optimization one and solved by using a genetic-like algorithm. Two numerical examples show the effectiveness of the method.
