To control the nonlinear effectively is the main problem of three-phase-four-line active power filter. Based on the circuit and mathematics model analysis of three-phase-four-line active power filter, Takagi-Sugeno (T-S) fuzzy logic model was established with feedback-control which directly controls the power system line currents and solves the nonlinear. Under condition of the stability of the proposed T-S fuzzy control model, parallel distributed compensation is employed to design fuzzy controllers, the stable feedback gains were obtained by linear matrix inequality. Computer simulations and experimentations tested on a three-phase-four-line APF system indicate the correctness and validity performance of fuzzy controlling with reactive power and harmonic compensation directly by this feedback controller.
