EIGENVALUE INCLUSION REGIONS AND THEIR USE IN THE ANALYSIS OF LINEAR AND NONLINEAR MULTIVARIABLE FEEDBACK SYSTEM.

Abstract:

The derivation of tight eigenvalue inclusion regions help extend the Generalised Nyquist criterion to the case of uncertain systems and lead to a necessary and sufficient Nyquist type of criterion for the case of unstructured perturbations. The approach provides an exact and immediate assessment of gain/phase margins. When applied to systems with nonlinearities which are sector bounded but otherwise unstructured, it produces a necessary and sufficient test for the circle criterion conditions ...
