摘要
Sufficient conditions are obtained for the eigenvalues of a discrete-time system to remain in a specified subregion in the unit circle with the centre at the origin in the complex plane in the presence of perturbations. The perturbations are allowed to be non-linear and time varying. Bounds are determined for linear state-space models using the Lyapunov theory. The bounds are derived for both highly and weakly structured perturbations. The results of the structured perturbations are then extended to interval matrices.
