Resumen de D-Stability radius of linear discrete time systems

Pham Huu Anh Ngoc, Toshiki Naito

• We study robustness of D-stability of linear difference equations under multiperturbation and affine perturbation of coefficient matrices via the concept of D-stability radius. Some explicit formulae are derived for these D-stability radii. The obtained results include the corresponding ones established earlier in Hinrichsen and Son and Ngoc and Son as particular cases.
