Abstract

This paper considers the global output feedback stabilization of a class of upper-triangular nonlinear systems with a single input and multiple output. It is shown that under a structural condition, the output feedback stabilization problem can be solved for this class of systems by coupling with a finite-time convergent observer and a saturated homogeneous stabilizer. More general results are also achieved for some complex nonlinear systems without the homogeneous growth condition.
