Static Gains Based Output Feedback Stabilization for a Class of Nonlinear Systems with Sensor Uncertainties

In this paper, the problem of global output feedback stabilization is addressed for a class of nonlinear systems with sensor uncertainties. To be specific, in the case of sensor sensitivity error and measurement deviation, a linear state observer and an output feedback controller are constructed on the basis of two static gains. It can be proved that all signals of the closed-loop system are globally bounded and that the system can achieve global stabilization. Simulation results are presented to show the effectiveness of proposed strategy.
