TS fuzzy based intelligent control of a three phase shunt filter under balanced and unbalanced conditions

This paper deals with an application of Takagi Sugeno (TS) fuzzy logic control in the operation of three phase shunt active power filter to achieve harmonic elimination and real power balance between supply and load. Unlike conventional controllers, fuzzy logic based controllers cover a wider range of operating condition, give allowance to uncertainties and are relatively much simpler to develop. Simulation studies using the TS fuzzy controllers in shunt active filter are already reported in the literature with encouraging results. This paper takes a step ahead and performs real time implementation of the intelligent controller thereby justifying its potentiality.
