摘要
This paper proposes a novel robust deadbeat control scheme for the active power filter with LCL input filter. The selection of the current loop gain is discussed by using root locus diagram representation to ensure stability of the closed-loop control algorithm. A feed-forward plus feedback control structure is adopted to achieve accurate steady-state performance and fast dynamic response by using the adaptive linear neural network (ANN) harmonic detection scheme. The validity of the control scheme is verified by the extensive simulation and experimental results.
