本文解决了动态控制器设计中大规模线性时不变（LTI）系统（例如大规模电力系统）中执行器最小放置的问题。提出了一种确保强结构可控（SSC）系统的新颖的充分必要条件。具体来说，本文解决了获得最小数量的专用输入的问题，即仅驱动单个状态变量的输入，以及它们应分配给的相应状态变量，使得 LTI 系统是 SSC。此外，还提出了一种高效且可扩展的算法，具有多项式实现复杂性，以实现专用输入的最小放置。在 IEEE 5 总线测试系统上提供了所提出的设计方法的说明，从而确定了要驱动的最小数量的物理状态变量，以确保强大的结构可控性。
This paper addresses the problem of minimal placement of actuators in large-scale linear time invariant (LTI) systems, such as large-scale power systems, for dynamic controller design. A novel sufficient and necessary condition to ensure a strong structurally controllable (SSC) system is proposed. Specifically, the paper addresses the problem of obtaining the minimal number of dedicated inputs, i.e., inputs which actuate only a single state variable, and the respective state variables they should be assigned to, such that the LTI system is SSC. In addition, an efficient and scalable algorithm, with polynomial implementation complexity, to achieve such minimal placement of dedicated inputs is proposed. An illustration of the proposed design methodology is provided on the IEEE 5-bus test system, thereby identifying the minimal number of physical state variables to be actuated for ensuring strong structural controllability.
