Abstract: |
A smooth robust dynamic feedback controller is constructed, and the problem of robust H_∞ almost disturbance attenuation with internal stability is solved for high-order nonlinear systems with parameter uncertainties.Finally,illustrative example and simulation results demonstrate the effectiveness of the proposed method. |
Key words: Nonlinear system.s Feedback H_∞ almost disturbance attenuation |
