Abstract
The problem of decentralized robust model following for a class of large scale interconnected systems with uncertainties is considered. Here, the bounds of uncertainties and interconnections are assumed to contain some unknown constants. For such a class of uncertain large scale systems, a class of decentralized adaptive sliding mode controllers is proposed by combining sliding mode controller with some adaptive laws which estimate unknown constants. The proposed controllers can guarantee that the tracking error between each subsystem and local reference model decreases asymptotically to zero and do not need the bounds of interconnection and the number of subsystems. Finally, an illustrative example is given to demonstrate the validity of the results.
