Linear stability theory

NettetIn this article, we present a stability analysis of linear time-invariant systems in control theory. The linear time-invariant systems under consideration involve the diagonal norm bounded linear differential inclusions. We propose a methodology based on low-rank ordinary differential equations. We construct an equivalent time-invariant system … Nettet1. Lyapunov stability theory was come out of Lyapunov, a Russian mathematician in 1892, and came from his doctoral dissertation. Until now, the theory of Lyapunov stability is still the main theoretical basis of almost all system-controller design (Chen, 1984 ). 2. First of all, the Lyapunov stability theory is understood through the picture.
