Abstract
The set invariability sufficient condition of discrete-time linear systems with disturbance and actuator saturation is given by using composite quadratic Lyapunov functions.We transform the condtion into linear matrix inequality(LMI) by Schur complement lemma
which may provide feasible method for the decision of set invariability.The result generalizes the conclusion in the existing articles about the set invariability condition
