Abstract
This research work deals with a hybrid control system based integrated Cuk converter fed brushless DC motor (BLDCM) for power factor correction. In this work, moth-flame optimization (MFO) and a fuzzy logic controller (FLC) have been combined and a moth-flame fuzzy logic controller (MFOFLC) has been proposed. Firstly, the BLDC motor modeling is composed with the power factor correction (PFC) based integrated Cuk converter and BLDC speed is regulated using variable DC-Link inverter voltage which results in a low switching operation with fewer switched losses. Here, with the use of a switched inductor, the task and execution of the proposed converter is redesigned. The DBR (diode bridge rectifier) trailed by a proposed PFC based integrated Cuk converter operates in discontinuous inductor conduction mode (DICM) for achievement of better power factor. MFO is exhibited for gathering of a dataset from the input voltage signal. At that point, separated datasets are sent to the FLC to improve the updating function and minimization of torque ripple. However, our main objective is to assess adequacy of the proposed method, but the power factor broke down. The execution of the proposed control methodology is executed in the MATLAB/Simulink working platform and the display is assessed with the existing techniques.
Highlights
Nowadays there is a trend to use a Brushless DC motor rather than a brushed DC motor in an expanding number of uses [1]
Enhancements of existing techniques are moth-flame optimization (MFO) and proportional Integral (PI) controller, which are equated versus the proposed method
The proposed strategy based BLDC motor was actualized in MATLAB/Simulink stage
Summary
Nowadays there is a trend to use a Brushless DC motor rather than a brushed DC motor in an expanding number of uses [1]. Compared to brush DC motors and induction motors, a BLDC motor has a couple of favorable circumstances [2]. It works as a synchronous motor in which the stator and rotor magnetic fields generate comparative frequencies. The BLDCM is made out of three stator coils with a permanent magnetic rotor in which the magnetic field is turned by two coils and a floating coil is responsible for back electro-motive force (EMF) [4]. Speed regulation is a fundamental viewpoint as far as BLDC speed and position controlling is concerned [5,6,7].
