This work is further focused on analyzing a bound for a reachable set of linear uncertain systems with polytopic parameters. By means of L-K functional theory and novel inequalities, some new conditions which are expressed in the form of LMIs are derived. It should be noted that novel inequalities can improve upper bounds of Jensen inequalities, which yields less conservatism of systems. Consequently, some numerical examples demonstrate that the authors' results are somewhat more effective and advantageous compared with the previous results.
这项工作进一步聚焦于分析具有多面体参数的线性不确定系统可达集的一个界。借助李雅普诺夫 - 克拉索夫斯基(L - K)泛函理论和新型不等式,推导出了一些以线性矩阵不等式(LMI)形式表示的新条件。应当指出的是,新型不等式能够改进詹森不等式的上界,这使得系统的保守性降低。因此,一些数值例子表明,与先前的结果相比,作者的结果更有效且更具优势。
