In the framework of AILC, Chen and Zhang  proposed an AILC scheme for a class of scalar systems with unknown time-varying parameters and unknown time-varying delay.
To the best of our knowledge, there is little work from the viewpoint of AILC to deal with nonlinear systems with time-delay and dead-zone nonlinearity in the literature at present stage.
In this paper, we present a novel AILC scheme for a class of nonlinear time-varying systems with unknown time-varying delays and unknown input dead-zone.
In order to clarify the main idea of AILC, we show the design procedure briefly by a simple scalar system running on [0, T] as follows:
The stability and convergence property of the proposed AILC scheme is summarized as follows.
In this section, a simulation example is presented to verify the effectiveness of the AILC scheme.
From the simulation results, we can see that the proposed AILC is effective in the sense that it can drive the tracking errors converge to zero along the iteration axis.
