H/sub /spl infin// control for a single-phase active power filter: a systematic approach

This paper shows the efficiency of the H/sub /spl infin// control design methodology for the case of the active filtering of single phase power networks. At first, a continuous time H/sub /spl infin// controller is designed which achieves all performances and robustness properties required. In particular, this approach allows one to choose the attenuation of each harmonic frequency independently of each other. Finally an effective 18th order discrete regulator is derived from the continuous one in an original way.
