A new slide mode controller is designed for AC servo system. The feed forwardsignal is used as average control, and fuzzy inference is used to regulate the magnitude of on-off control.
It is concluded that the harmonic and reactive current detection behave as just a feed-forwardsignal in this closed-loop, and it is incapable of improving the compensation accuracy in steady-state.
