Implementation of adaptive fuzzy logic and PI controllers to regulate the DC bus voltage of shunt active power filter

- The output gain of the adaptive fuzzy controller (AFC), it is considerate as a fuzzy variable.
- This gain is adapted as a function of the voltage error and its variation.
- The comparative at PI controller study, shows that the adaptive fuzzy controller can be enhance the performances the DC voltage control at various operating.
- Experimental results validate the design methodology.
