| Abstract: | On the Estimation of Upper and Lower Bound for Solutions to Perturbed Discrete Riccati EquationsAbstract: The estimation of the positive definite solution of perturbed discrete Riccati equations is discussed.Several upper bounds and lower bounds of the positive definite solution are obtained under the condition that the perturbation parameters are norm-bounded uncertain.The calculation of the bounds are given by definite Riccati equation,thus it is avoided to solve high order algebraic equations.The validity of the method is validate by numerical examples. |
