Continuous output feedback stabilization for nonlinear systems based on sampled and delayed output measurements

Yanjun Shen, Daoyuan Zhang, Xiaohua Xia
This paper addresses the problem of output feedback stabilization for nonlinear systems with sampled and delayed output measurements. Firstly, sufficient conditions are proposed to ensure that a class of hybrid systems are globally exponentially stable. Then, based on the sufficient conditions and a dedicated construction continuous observer, an output feedback control law is presented to globally exponentially stabilize the nonlinear systems. The output feedback stabilizer is continuous and
