The estimation of the positive definite solutions to perturbed discrete Lyapunov equa- tions is discussed. Several upper bounds of the positive definite solutions are obtained when the perturbation parameters are norm-bounded uncertain. In the derivation of the bounds, one only needs to deal with eigenvalues of matrices and linear matrix in- equalities, and thus avoids solving high-order algebraic equations. A numerical example is presented.
