本说明涉及最大集合的研究,相对于最大集合,集合是正不变的,并且,给定集合 a,/spl Delta/-p.i 的一些属性。集进行分析。该方法使用 d'Alessandro 和 De Santis (1991) 中引入的后向递归的一步,其中分析了线性动态输入和/或状态约束系统的可行性和最优性条件。在第二节中,作者给出了主要定义和一些基本结果。在随后的第三节中 /spl Delta/-p.i 的一些属性。集进行调查。第四节分析了多面体集合的特殊情况。在第五节中,作者展示了在动态矩阵 A 中具有参数不确定性的线性系统中的应用。作者开发了一种技术来确定参数空间中的集合,使得对于集合中参数的任何值,状态空间中的给定集合是正不变的。最后一节给出了一个数值示例。 >
This note concerns the investigation of maximal sets, with respect to which a set is positively invariant, and, given a set a, some properties of /spl Delta/-p.i. sets are analyzed. The approach uses one step of the backward recursion introduced in d'Alessandro and De Santis (1991), where feasibility and optimality conditions for linear dynamical input and/or state constrained systems were analyzed. In Section II, the author gives the main definitions and some basic results. In the subsequent Section III some properties of /spl Delta/-p.i. sets are investigated. The particular case of polyhedral sets is analyzed in Section IV. In Section V, the author shows an application to linear systems with parametric uncertainties in the dynamic matrix A. The author develops a technique to determine a set in the parameters space such that, for any value of the parameter in the set, a given set in the state space is positively invariant. In the last section a numerical example is developed. >
