Abstract
The article presents the design and implementation of a hybrid fuzzy poisson fractional order proportional integral derivative controller (h-FL-PO-FPID controller) in the wind-driven permanent magnet synchronous generator (PMSG). The h-FL-PO-FPID controller is a hybrid controller that is formed by the combination of a fuzzy logic controller, a poisson distribution (PO), a fractional order proportional integral, and a derivative (FO-PID) controller. The integration of PMSG with the grid via rectifier and inverter has many challenges, like high peak overshoot, large settling time, more harmonics at the output end, and an inappropriate voltage profile. The total harmonic distortion (THD) is used to measure the harmonics. The PMSG is driven by a wind turbine. The rectifier & inverter controlling has been done with fuzzy logic controllers (FLC), FO-PID controllers, and proportional integral and derivative (PID) controllers. A closed-loop current control mechanism has been developed for controlling the rectifier and inverter with the given three methods. It is observed that peak overshoot (%) and settling time (sec) of the DC link voltage and rotor speed are found to be minimum with h-FL-PO-FPID in comparison to FLC, FO-PID, and PID existing methods under various loading conditions.In addition to this, an improved voltage profile is obtained with h-FL-PO-FPID in comparison to other methods, which means the least THD (%) of the three-phase voltage is attained with h-FL-PO-FPID with respect to other and existing methods under various loading conditions.
