Comparison the Performance of the Dynamic Voltage Restorer Based on PI, Fuzzy Logic, and Fuzzy Neural Controller

The Dynamic Voltage Restorer (DVR) is one of the most efficient and effective custom power devices in protecting sensitive equipment against voltage sag harmonics due to; lower cost, smaller size dynamic response. inverter core DVR it directly affects performance DVR, incorrect injection or delay process would be dangerous to loads. major functions controller are, detection disturbances events system, calculation compensating generation reference signal for PWM trigger source inverter. PI fuzzy logic has been compared with proposed neural optimized correcting problems mitigating distortion linear non-linear Fuzzy Neural Logic improving any kind variations reducing Total Harmonic Distortion (THD) by enhancing an capability which highly influenced a control algorithm employed. system simulated MATLAB results confirm validity feasibility.
