The well known open Černý conjecture states that each synchronizing automaton with n states has a synchronizing word of length at most (n−1) . On the other hand, the best known upper bound is cubic of n. Recently, in the paper [1] of Alessandro and Carpi, the authors introduced the new notion of strongly transitivity for automata and conjectured that this property with a help of Extension metho...

This paper presents an adaptive actuators allocation scheme that is fault-tolerant with respect to actuator faults or loss of effectiveness. The main idea here is to use an ad-hoc online parameter estimator coupled with an allocation algorithm to perform on-line control reconfiguration. Two simple algorithms are proposed for nonlinear discrete-time systems. The main properties of the algorithms...
