Voltage Sag Compensation by Use of Dynamic Voltage Restorers with Adaptive Fuzzy Controllers

摘要

In this paper the fuzzy logic controllers (FLCs) gives to be the special arrangement when the process is uncooperative complex for investigation by conventional procedure or when the accessible data information are interpreted subjectively, estimated. In writing, the present FLCs all in all comprises of two input sources (error and change) and one output. The number of membership functions is chosen in most cases to be five or seven regardless of the approach used for the design. In this paper, we present Adaptive Fuzzy Controllers (AFCs) way to deal with improve the two sources of inputs one output FLCs. Adaptive Fuzzy Controllers provides fast response and better %THD compared to Fuzzy and PR controller..........
