Output Feedback Sampled-Data Control of Nonlinear Systems in Output Feedback Form

This paper deals with sampled-data control of nonlinear systems in the output feedback form. A sampled-data control strategy is proposed based on the existing control design in the continuous-time domain via output feedback. The proposed control uses the sampled output and a discrete-time implementation of filters involved. The overall stability of the system under the proposed control has been analyzed, and the semi-global asymptotic stability for the system with relative degree one and two is established by keeping the sampling interval with a specified range.
