Output feedback control design for a class of nonlinear fractional-order lower triangular systems

摘要

The output feedback stabilizing controller for nonlinear fractional-order triangular systems is designed by using the Lyapunov function method. The output feedback controller is given by introducing appropriate transformations of coordinates. By means of the Lypaunov-liked method, the output feedback controller makes the closed-loop system asymptotically stable. An example is given to testify the validity of main results.
