具有稀疏控制的线性动力系统的输出能控性

Output Controllability of a Linear Dynamical System with Sparse Controls

Geethu Joseph

摘要:

本文研究了离散线性系统在稀疏控制输入下保证输出可控所需满足的条件。通过推广Kalman秩检验,可以直接得到输出能控性的一组充分必要条件。然而,这些条件的验证是计算繁重,由于其组合性质。因此,我们推导出输出稀疏可控性的非组合条件,这些条件可以用多项式时间复杂度来验证。我们的研究结果还提供了所需的最小稀疏水平,以确保系统的输出可控性的界限。这种额外的洞察力对于设计稀疏控制输入非常有用,可以将系统驱动到任何期望的输出。

英文摘要:

In this paper, we study the conditions to be satisfied by a discrete-time linear system to ensure output controllability using sparse control inputs. A set of necessary and sufficient conditions can be directly obtained by extending the Kalman rank test for output controllability. However, the verification of these conditions is computationally heavy due to their combinatorial nature. Therefore, we derive non-combinatorial conditions for output sparse controllability which can be verified with polynomial time complexity. Our results also provide bounds on the minimum sparsity level required to ensure output controllability of the system. This additional insight is useful for designing sparse control input that drives the system to any desired output.
