The H-inf solution in effect minimizes the effects of a worst case disturbance.
How can one design a H-Inf controller to attenuate specific disturbance waveforms ? In other words, if I know I have an unknown step disturbance or a triangular waveform to reject, how would I go about doing that.
One possible way to deal with would be to incorporate an internal model. Is this the only way?
I would appreciate any pointers to papers or literature that addresses the above,
thanks in advance lt
