A harmonic disturbance observer for nonlinear systems
A nonlinear harmonic disturbance observer for nonlinear systems
subject to harmonics is designed and stability of the proposed
observer is established using passivity approach. A systematic
procedure to choose the nonlinear gain function in the
observer is proposed. The proposed nonlinear disturbance observer
can be integrated with a linear/nonlinear controller to
improve its disturbance attenuation ability for nonlinear systems
under harmonics.
