Global exponential stabilization for a class of uncertain nonlinear systems with time-varying delay arguments and input deadzone nonlinearities

In this paper, the global exponential stabilization for a class of uncertain nonlinear systems with time-varying delay arguments and input deadzone nonlinearities is considered. A composite feedback control is proposed such that the feedback-controlled system is globally exponentially stable if a simple sufficient condition is met. Furthermore, for slightly more restricted systems, we show that the global exponential stability can always be achieved with any pre-specified convergence rate. A numerical example is provided to illustrate the use of our main results.
