Abstract:

By using the method of dynamic high gain, homogeneous theory, Lyapunov theory and finite time stable theory, an output feedback controller were designed for a class of SISO nonlinear systems. The output feedback controller consists of linear parts and nonlinear parts. The linear parts can make sure the zero solution of the closed-loop system is globally asymptotically stable and the nonlinear parts can ensure the zero solution of the closed-loop system is locally finite time stable. Final, an example was presented to illustrate the effectiveness of the method.

Key words: nonlinear system; finite time stability; output feedback control
