“…Note that in the literature, a different concept of FTS can also be found, where it is required that, given an initial condition, the state trajectories converge to the zero equilibrium in a finite time interval, see [16,23,24,25]; based on Lyapunov stability criteria, the asymptotic convergence is transformed to finite time convergence. Recent results achieved, considering the control problem of finite horizon estimation in the presence of noise for linear time-varying systems [27].…”
