| Summary: | In this paper, we study a general class of strict
feedback nonlinear systems, where the input signal takes quantized
values. We consider a stabilization problem for nonlinear
uncertain systems via adaptive backstepping approach. The
control design is achieved by introducing a hysteretic quantizer to
avoid chattering and using backstepping technique. A guideline
is derived to select the parameters of the quantizer. The designed
controller together with the quantizer ensures the stability of the
closed loop system in the sense of signal boundedness.
