On the finite time stabilization via robust control for uncertain disturbed systems
Patricio Ordaz, Hussain Alazki, Bonifacio Sánchez, Mario Ordaz-Oliver
Abstract
This paper deals with the finite-time stabilization problem for a class of uncertain disturbed systems using linear robust
control. The proposed algorithm is designed to provide the robustness of a linear feedback control scheme such that system
trajectories arrive at a small-size attractive set around an unstable equilibrium in a finite time. To this end, an optimization
problem with a linear matrix inequality constraint is presented. This means that the effects of external disturbances, as well
as matched and mismatched uncertain dynamics, can be significantly reduced. Finally, the performance of the suggested
closed-loop control strategies is shown by the trajectory tracking of an unmanned aerial vehicle flight.
