摘要
This paper presents a dedicated micro-controller based fuzzy logic controller for three-phase shunt active power filter. It is used to improve power quality by compensating harmonics and reactive power requirement of non-linear loads. The compensation process proposed is simple, which is based on sensing line currents and regulating the dc link voltage. It operates without sensing the harmonic or reactive volt-ampere requirement of the load. Fuzzy logic control is used to regulate the dc link voltage in place of the conventional PI controller, as the fuzzy control is based on simple linguistic variables and does not require the mathematical model of the system. Response of the fuzzy controller is compared with the conventional PI controller by simulation study. An attempt is made to implement a complex control like fuzzy logic on an inexpensive 8-bit micro-controller (INTEL 8031). Various experimental results are presented under steady state and transient conditions.
