Abstract
In the previous work of Huang et al a coordinated decentralized hybrid adaptive output feedback fuzzy control scheme of largescale nonlinear systems is obtained predicated upon this prerequisite assumption that the local controllers can share the a priori information about their individual reference models In this note we concentrate in the absence of the coordination assumption on developing a classical decentralized combined indirect and direct adaptive fuzzy controller for a class of uncertain largescale nonlinear systems The output feedback and adaptation mechanisms proposed for each subsystem hinges just upon its individual output regardless of any other output reference Neither the famous strictly positive real SPR condition nor a highgain observer HGO is required to realize the overall output feedback algorithm The tracking errors of the closedloop largescale system are shown to converge to tunable neighborhoods of the origin Simulation results on correlated inverted pendulums verify the validity of the decentralized controller modification
