Decentralized adaptive sliding mode controllers for a class of large scale interconnected systems with uncertainties

The problem of decentralized robust controllers for a, class of uncertain large scale interconnected systems is considered. It is assumed that uncertainties and interconnections satisfy the so-called matching conditions and their bounds contain some unknown constants. For such unknown bounds, a modified adaptive law is proposed. By combining a sliding mode controller with the modified adaptive law, we construct a decentralized adaptive sliding mode controller. Finally, a numerical example is given to demonstrate the validity of the results.
