In this paper, we discuss the decentralized adaptive output feedback control problem for uncertainly large-scale systems, and the uncertainties satisfy the usual matching conditions. Aiming at the problem that the uncertain boundary is unknown, the adaptive asymptotic stability of the system is achieved by designing an adaptive output feedback controller. Simulation results show that the design method of this paper is effective.
