最小成本约束下的投入产出与控制配置协同设计问题:一种结构系统方法

Minimum Cost Constrained Input-Output and Control Configuration Co-Design Problem: A Structural Systems Approach

Sergio Pequito, Soummya Kar, George J. Pappas

摘要:

本文研究了最小成本约束下的输入输出与控制组态协同设计问题。给定一个线性时不变的植物,其中可能的输入和输出的集合是已知的先验,我们的目标是确定的输入,输出和它们之间的通信的集合招致的最小成本,从而确保所需的控制性能,测量的任意极点配置能力的闭环系统。我们表明,这个问题是NP-困难的一般(在状态空间的大小)。然而,子类的问题,其中的动态矩阵是不可约的,被证明是多项式可解的,并提出了相应的算法。此外,在相同的假设下,可以使用相同的算法来分别解决最小成本约束的I/O选择问题和最小成本控制配置选择问题。为了说明本文的主要结果,还提供了一些模拟。

英文摘要:

In this paper, we study the minimal cost constrained input-output (I/O) and control configuration co-design problem. Given a linear time-invariant plant, where a collection of possible inputs and outputs is known a priori, we aim to determine the collection of inputs, outputs and communication among them incurring in the minimum cost, such that desired control performance, measured in terms of arbitrary pole-placement capability of the closed-loop system, is ensured. We show that this problem is NP-hard in general (in the size of the state space). However, the subclass of problems, in which the dynamic matrix is irreducible, is shown to be polynomially solvable and the corresponding algorithm is presented. In addition, under the same assumption, the same algorithm can be used to solve the minimal cost constrained I/O selection problem, and the minimal cost control configuration selection problem, individually. In order to illustrate the main results of this paper, some simulations are also provided.
