摘要:

本文提出方法用于处理具有分布延迟的线性耦合微分-差分延迟系统(CDDS)在耗散约束下的延迟范围稳定性分析问题。线性CDDS模型包含许多线性延迟系统作为特殊情况。一种具有非常数矩阵参数的新Lyapunov-Krasovskii泛函被应用于推导稳定性条件,这些参数与延迟值多项式相关。通过构造这种新泛函,可以推导出以鲁棒线性矩阵不等式(LMIs)形式的充分条件,保证在耗散约束下线性CDDS的范围稳定性。为了解决由此产生的鲁棒LMIs,我们应用求和平方编程技术与矩阵松弛方法,不引入任何潜在的保守性。此外,所提出的方法可扩展用于解决具有预设耗散约束的线性CDDS的延迟裕度估计问题。最后,通过数值例子展示了所提出方法的有效性。

英文摘要:

This paper proposes methods to handle the problem of delay range stability analysis for a linear coupled differential-difference system (CDDS) with distributed delays subject to dissipative constraints. The model of linear CDDS contains many models of linear delay systems as special cases. A novel Liapunov-Krasovskii functional with non-constant matrix parameters, which are related to the delay value polynomially, is applied to derive stability conditions. By constructing this new functional, sufficient conditions in terms of robust linear matrix inequalities (LMIs) can be derived, which guarantee range stability of a linear CDDS subject to dissipative constraints. To solve the resulting robust LMIs numerically, we apply the technique of sum of squares programming together with matrix relaxations without introducing any potential conservatism to the original robust LMIs. Furthermore, the proposed methods can be extended to solve delay margin estimation problems for a linear CDDS subject to prescribed dissipative constraints. Finally, numerical examples are presented to demonstrate the effectiveness of the proposed methodologies.
