Uniting Control for Finite Time Stabilization of Nonlinear Detectable Systems

The stabilization of nonlinear systems under zero-state-detectability assumption or its analogues is considered. The proposed supervisory control provides a finite time practical stabilization of output and it is based on uniting local and global controllers. The global control ensures boundedness of solutions and output convergence to zero, while local one ensures finite time convergence to a predefined set into the zero dynamics set. Computer simulation illustrates advantages of the proposed algorithm.
