A Shortest-Path Lyapunov Approach for Forward Decision Processes by Julio B. Clempner

“…The trajectory over the net is calculated forward using a discrete Lyapunov-like function, considered as a distance function. Because a Lyapunov-like function is a solution to a difference equation, it is constructed to respect the constraints imposed by the system (a Euclidean metric does not consider these factors). …”

Design of Arbitrary Time Convergence Controller for n-th Order System by Nianhao Xie, Kebo Li, Wenshan Su, Lei Chen

“…Herein, the arbitrary time convergence controller is improved, the unified formula for n-th order system is given, and a more accurate control parameter range is obtained. By constructing an ingenious auxiliary function and a novel Lyapunov function, the arbitrary time convergence of the n-th order controller is proved, and the reasonable parameter selection range is obtained using the integrator backstepping and the mathematical induction method. …”
