Tracking Design for Uncertain Time-Delay Systems with Pure-Feedback Terms

This paper addresses the tracking design issue for the nonlinear time-delay switched systems (NTDSSs) with unknown pure-feedback terms. The pure-feedback terms can be indifferentiable and the controllability of each subsystem is not required. We use the neural networks approach to approximate these unknown feedback terms, and a stabilizing switching law is co-designed to construct a controller, under which the trajectory of the closed-loop NTDSSs are bounded, and the tracking problem is addressed. Finally, we give an example to verifies the methods.
