摘要：The problem of saturated output feedback stabi-lization for a class of nonlinear systems with upper-triangularstructure is addressed in this paper. By constructing a reducedorder observer to estimates the unmeasurable states and byskillfully using the homogeneous domination approach andthe nested saturation technique, a saturated output feedbackcontrol scheme is successfully developed. It is prove that theproposed controller with appropriate design parameters canrender the states of the closed-loop system globally asymp-totically to zero without violation of the input constraint. Asimulation example is provided to demonstrate the effectivenessof the proposed method.
