Sample-Data-Based Stabilization of a Class of Switched Nonlinear Systems with Unknown Output Function

In this paper, the problem of sampled-data output feedback control is discussed for a class of switched nonlinear systems with imprecise output information. First, with the help of a compensator, an output feedback controller in the form of continuous-time is designed on the basis of backstepping design method and the domination approach. Then, by discretizing the continuous-time one, we obtain the sampled-data output feedback controller by skillfully choosing design parameters and a maximum sampling period, which ensures the global exponential stability for the closed-loop system. Finally, a numerical example is presented to illustrate the validity of the result.
