Exponential Stabilizability of Switched Systems with Polytopic Uncertainties

Abstract EN

The exponential stabilizability of switched nonlinear systems with polytopic uncertainties is explored by employing the methods of nonsmooth analysis and the minimum quadratic Lyapunov function.

The switchings among subsystems are dependent on the directional derivative along the vertex directions of subsystems.

In particular, a sufficient condition for exponential stabilizability of the switched nonlinear systems is established considering the sliding modes and the directional derivatives along sliding modes.

Furthermore, the matrix conditions of exponential stabilizability are derived for the case of switched linear system and the numerical example is given to show the validity of the synthesis results.
