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

摘要

This paper addresses the problem of output feedback stabilization for nonlinear systems with sampledand delayed output measurements. Firstly, sufficient conditions are proposed to ensure that a class ofhybrid systems are globally exponentially stable. Then, based on the sufficient conditions and a dedicatedconstruction continuous observer, an output feedback control law is presented to globally exponentiallystabilize the nonlinear systems. The output feedback stabilizer is continuous and hybrid, and can be derivedwithout discretization. The maximum allowable sampling period and the maximum delay are also given.At last, a numerical example is provided to illustrate the design methods.
