I. Introduction
Finite-time control through continuous feedback has been a research topic of increasing interest in the last few years. Such an intriguing topic has attracted attention on its need for a suitable analytical framework around its conceptualization and characterization. In this direction, important contributions have been developed for autonomous systems in the works of Bhat and Bernstein [2], [3], by stating a precise definition of a finite-time stable equilibrium, a Lyapunov-function-based criterion for its determination, and a useful characterization for homogeneous vector fields.
