A novel H_∞tracking-based decentralized indirect adaptive output feedback fuzzy controller for a class of uncertain large-scale nonlinear systems is developed.By virtue of the proper filtering of the observation error dynamics,the observer-based decentralized indirect adaptive fuzzy control scheme is presented for a class of large-scale nonlinear systems using the combination of H_∞tracking technique,a fuzzy adaptive observer and fuzzy inference systems.The output feedback and adaptation mechanisms are both robust and implementable indeed owing to their freedom from the unavailable observation error vector.All the signals of the closed-loop largescale system are guaranteed to stay uniformly bounded and the output errors take on H_∞tracking performance. Simulation results substantiate the effectiveness of the proposed scheme.
