Global Output Feedback Stabilization for a Class of Nonlinear Cascade Systems

Abstract EN

This paper focuses on the problem of global output feedback stabilization for a class of nonlinear cascade systems with time-varying output function.

By using double-domination approach, an output feedback controller is developed to guarantee the global asymptotic stability of closed-loop system.

The novel control strategy successfully constructs a unified Lyapunov function, which is suitable for both upper-triangular and lower-triangular systems.

Finally, two numerical examples are provided to illustrate the effectiveness of a control strategy.
