Webb11 dec. 2024 · Slowly varying systems are common in physics and control engineering and thus stability analysis for those systems has drawn considerable attention in the literature. This paper uses the “frozen time approach” to derive Lyapunov inequality conditions for the stability of a wide class of slowly varying systems. Webb6 juni 2024 · and if $\alpha=0$ it is called slowly varying (at infinity). Since $t^0=1,$ this coincides with the definition in Wikipedia of slowly varying functions: a slowly varying function in which the relative differences in the tail is equal to zero: $$\lim_ {x\to \infty} \frac {f (tx) - f (x)} {f (x)}=0.$$
