This paper proposes the decentralization of interconnected descriptor system through estimation of disturbance. A noticeable problem in the decentralization is how to handle interacting terms exchanging among each local subsystems. This interacting term can be derived from steady-state response of slow-mode system stabilized by feedback control law. But, the derived one cannot be directly applied in the decentralization owing to possessing the global disturbance signal. This difficulty will be coped with estimating the global disturbance using the sliding mode observer, which includes feedforward injection map and compensation signal. Finally, the effectiveness of proposed method will be proved through the results of the numerical simulation.
