This paper presented a discrete-time integral sliding mode control for a large-scale system with unmatched uncertainty. A new theorem is presented and proved that the controller is able to handle the effect of interconnection for the large-scale systems and unmatched uncertainty, and the system stability is ensured. The controller will ensure the system achieve the quasi-sliding surface and remains on it. The results showed a fast convergence to the desired value and the attenuation of disturbance is achieved.
