Adaptive Robust Stabilization for a Class of Uncertain Linear Systems via Variable Gain Controllers

This paper discusses a problem of adaptive robust stabilization for a class of uncertain linear systems via variable gain controllers. The uncertainties under consideration which are composed of matched part and unmatched one are bounded, but its upper bounds are unknown. In this paper, on the basis of piecewise Lyapunov functions, we present a design method of the adaptive robust control system. Finally, illustrative examples are presented
