Intelligent Tuned Hybrid Power Filter with Fuzzy-PI Control

With the growing impact of power regulators, machines, and other electronic devices on quality utility electric service, harmonics has recently emerged as a major research topic in area energy consumption. In this work, fuzzy intelligent inductor–capacitor–inductor hybrid filter is designed to reduce distribution line. The shunt active passive design consideration have been improved. Since nature proportional integral control only efficient with linear variations real condition system always varying nonlinearly, create minimum steady error, fuzzy-tuned intelligently consider input changes revise decision rules using reasoning. content harmonic current respect load momentarily commutated. Thus, Clarke’s transformation, errors are summed instantaneous that converted compensation hysteresis band monitored pulse generator. output would turn off IGBT inverter’s switches, supplying reject harmonics. overall work was tested MATLAB/SIMULINK® effective canceling
