Compared to the proportional-integral strategy, repetitive control strategy possesses high suppression ability for alternating current (AC) harmonics of signals. Thus, RC controllers are widely used in closed-loop systems suppress periodic harmonics. In order further improve brushless DC (BLDC) motor operation performance, a frequency adaptive controller (FARC) is proposed, and then novel loop ...
