摘要:

本文研究了一类由Delta算子描述的分段线性系统的二次稳定性问题。基于Delta域的Lyapunov稳定性理论,利用S-procedure构造了分段Lyapunov函数,而且将分段线性Delta 算子系统的二次稳定性判问题转化为一组线性矩阵不等式的求解问题。

Abstract:

A quadratic stability analysis method of the Delta operator formulated piecewise linear system is considered in this paper. Based on the theory of the Lyapunov stability, a piecewise Lyapunov function is constructed using S-procedure. Furthermore, the function can be obtained by solving a set of linea r matrix inequalities (LMI)
