Adaptive Output Feedback Control for A Class of Nonlinear Time-Delay Systems with Input and Output Quantization

This paper studies the problem of adaptive output feedback control for a class of nonlinear time-delay systems. Both the input and output signals of the system are quantized for the sake of less communication burden. The nonlinearities satisfy linear growth condition on the unmeasurable states with unknown growth rate. With the combination of dynamic high-gain technique and sector bound approach, a linear-like quantized controller is constructed to compensate for the quantization error. It is proved that the proposed adaptive quantized control schema can guarantee that all signals in the closed-loop system are bounded.
