Embodiment Construction
[0048] The active power filter FNN control method based on fuzzy inversion is characterized in that: comprise the steps: Step (A) establishes the active power filter mathematical model with disturbance and error according to circuit theory and Kirchhoff's theorem; Step (B) the inverse controller and the sliding mode surface of the design active power filter; Step (C) the fuzzy neural network controller and the adaptive law thereof of the design active power filter, constitute the self-adaptive fuzzy neural network controller; Step (D) designing the fuzzy controller and its adaptive law of the active power filter to form an adaptive fuzzy controller;
[0049] Among them, the virtual control quantity It is connected in series with the sliding surface, then connected in series with the adaptive fuzzy neural network controller in parallel with the adaptive fuzzy controller, and finally connected in series with the output of the active power filter and fed back to the virtual cont...
