Abstract
Control strategies for extracting the three-phase reference currents for shunt active power filters are compared, evaluating their performance under different source conditions with PI and Fuzzy Controllers in MATLAB/Simulink environment When the supply voltages are balanced and sinusoidal, the two control strategies are converge to the same compensation characteristics; However, the supply voltages are distorted and/or un-balanced sinusoidal, these control strategies result in different degrees of compensation in harmonics. The compensation capabilities are not equivalent, with p - q control strategy unable to yield an adequate solution when source voltages are not ideal. Extensive simulations are carried out with PI controller and also with Fuzzy controller for both p-q and I<sub>d</sub>-I<sub>q</sub> control strategies under different main voltages. Extensive Simulations are carried out with PI as well as fuzzy controller for both p-q and I<sub>d</sub> - I<sub>q</sub> control strategies by considering different voltage conditions and adequate results were presented. On owing I<sub>d</sub> - I<sub>q</sub> method with fuzzy logic controller gives away an out-standing performance under any voltage conditions (balanced, un-balanced, balanced and non-sinusoidal).
