A fuzzy logic controller for an active power line conditioner (APLC) is described. Frequency-domain analysis is used to determine the desired compensation current, and a rule-based piecewise linear fuzzy proportional-integral controller (FPIC) provides the appropriate switching pattern of the APLC to generate the actual compensation current. Both MATLAB simulations and experimental measurements on a low-power, digital signal processor (DSP) based, hardware prototype are described. The simulations and measurements agree very well and show that the APLC/FPIC system can significantly improve both total harmonic distortion and power factor during both steady-state and transient operating conditions.
