摘要

基于特定的续分展开、欧氏除法方案和 Faddeev-LeVerrier 算法,我们提出了一种线性时不变控制系统稳定性分析的创新方法。我们的方法提供了一个全面的分析框架,有助于确定闭环系统稳定控制器增益的范围,无论是频域还是状态空间。与 Routh-Hurwitz 准则不同的是,我们的技术不受特定情况下临时规则的限制,从而提高了分析的严谨性。此外,在某些情况下,我们的方法可以识别中游的不稳定性,从而节省计算资源。所提出的方法概念清晰,易于实施,三个示例即为例证。

Stability Analysis of Linear Control Systems by Wall’s Continued Fraction Expansion

Stability Analysis of Linear Control Systems by Wall’s Continued Fraction Expansion

Based on a particular continued fraction expansion, the Euclidean division scheme, and the Faddeev–LeVerrier algorithm, we propose an innovative approach to stability analysis for linear time-invariant control systems. Our method offers a comprehensive analytical framework that facilitates the determination of the range of stable controller gains for closed-loop systems, whether presented in the frequency domain or the state space. Unlike the Routh–Hurwitz criterion, our technique is exempt from the ad hoc rules that govern specific cases, thus advancing analytical rigor. Moreover, in certain scenarios, our method allows for the identification of instability midstream, thereby conserving computational resources. The proposed method is conceptually lucid and readily implementable, as exemplified by three illustrative instances.
