摘要:

S-引理是运筹学领域和控制论领域中一个十分重要的定理。本文首先从一个非线性控制系统的全局渐近稳定性分析出发,引出S-过程和S-引理,以及两者之间的联系与区别。接着我们介绍了S-引理的基本内容和最新进展,以及它在复数域和四元数集合上的推广。最后,我们介绍了将齐次型S-引理推广到任意多个对称(或厄米特)矩阵时的一些基本结果。

关键词: S-过程, S-引理, 袁氏引理, 低秩解

Abstract:

S-lemma is an important theorem in operations research and cybernetics. In this paper, starting from verifying the global asymptotic stability of a nonlinear control system, we draw S-procedure, S-lemma, and their relations and differences. Then the basic content of S-lemma and its latest advances are introduced. Moreover, several generalizations of S-lemma over the complex field and the quaternion set are discussed. Finally, some basic results corresponding to S-lemma are showed for any number of symmetric (or Hermitian) matrices.

Key words: S-procedure, S-lemma, Yuan's lemma, low-rank solutions
