An invariance principle for time-varying systems
An invariance principle for time-varying systems is a scholarly work by Edward J Hancock and Antonis Papachristodoulou, published in 2012. The main subjects of the publication include mathematics, mathematical analysis, missile guidance, property, bounded function, simple, pendulum, applied mathematics, bifurcation theory, limit, limit set, invariance principle, and mobile robot. The authors first present a novel proof of the Krasovskii-Lasalle invariance principle for forward time using invariance properties of regions of attraction, rather than the invariance property of the limit set.
