This paper proposes two regional stability conditions, equivalently analysis conditions of the region of attraction, for linear time (LTI) sustems with saturations. We consider two analysis approaches in order to derive the conditions. One is an extension of Park’s condition in the case of non-zero direct-feedthrough matrix from output to input of the saturation. The other is a transformation from the condition for discrete time systems to a condition for continuous time systems. Finally, we show that the derived conditions are less conservative than the existing results by numerical examples.
