GLOBAL STABILIZATION OF A CLASS OF UNCERTAIN NONLINEAR DYNAMIC SYSTEMS VIA LINEAR CONTROL

摘要

In this paper, the stabilization of a class of uncertain nonlinear dynamic systems is considered. The proposed controller is based on a optimal control problem. The global practical stability is guaranteed by the proposed control; moreover, both the radius of the final attractor and the exponential rate of convergence toward any final attractor can be arbitrarily chosen. An example illustrates the effectiveness of the proposed method.
