The modeling of BLDC motor and performance analysis under diverse operating speed settings has been presented in this paper. BLDC motors gaining more & more attention from different Industrial and domestic appliance manufacturers due to its compact size, high efficiency and robust structure. Voluminous research and developments in the domains of material science and power electronics led to substantial increase in applications of BLDC motor to electric drives. This paper deals with the modeling of BLDC motor drive system along with a comparative study of modified queens bee evolution based GA tuned & manually tuned control schemes using MATLAB /SIMULINK. In order to evaluate the performance of proposed drive, simulation is carried out at different Mechanical load & speed conditions. Test outcomes thus achieved show that the model performance is satisfactory.

“…Accordingly, two equivalent zero-voltage space vectors were obtained in each sector, as depicted in Table 3. The most recent and best performing DTC strategy was proposed by Mourad et al [20]. It offered improved reliability by achieving balanced switching frequencies of inverter upper and lower insulated gate bipolar transistors on the one hand, and reduction of the average value of motor common-mode voltages on the other hand.…”

Original scientific paperThe micro all-electric vehicle pertaining to this study is rear-driven, with motors in the left and right rear wheels. The motors are brushless dc (BLDC) using Hall effect sensors with a trapezoidal back-electromotive force. The control system is developed by using a digital signal processor. To thoroughly utilize the fast torque generation feature of BLDC motors, direct torque control (DTC) is preferable, but with conventional DTC, dead-time must be added. This paper proposes an improved DTC, where the switching device operating principle is equivalent to that of a unipolar pulse width modulation (PWM) technique named PWM-ON. Dead-time is not required, and switching losses are reduced. Further analysis showed that under the improved DTC the dc supply took up only the load current, confirming that there was no return of load energy to the dc supply, which protects the batteries. Experimental results are given to confirm validity.

Električno malo vozilo razmatrano u ovomečlanku ima pogon na stražnje kotače, gdje su motori smješteni u lijevi i desni stražnji kotač. Motori su istosmjerni bezčetkica (BLCD) te koriste senzore zasnovane na Hallovom efektu s trapezoidalnom elektromotornom silom. Upravljački sustav razvijen je na digitalnom raču-nalu. Kako bi se iskoristila mogućnost stvaranja bzrog momenta, što je jedno od prednosti BLCD motora, preferira se direktno upravljanje momentom (DTC), ali kod konvencionalnog DTC-a potrebno je dodati mrtvo vrijeme. U ovomečlanku je predložena unaprije ena verzija DTC-a, gdje princip rada invertora isti kao i kod unipolarne pulsnoširinske modulacije (PWM-ON). U ovome slučaju mrtvo vrijeme nije potrebno te se smanjuju gubici u invertoru. Daljnja analiza je pokazala da s unaprije enim DTC-om nema povratka energije, što štiti baterij. Eksperimentalni rezultati su dani kako bi se potvrdila ispravnost pristupa.Ključne riječi: istosmjerni motor bezčetkica, mrtvo vrijeme, direktno upravljanje momentom, električna vozila, mala električna vozila

Abstract:The mathematical model of the equivalent circuit of a brushless DC motor switches during the operation due to commutation. This issue causes a sudden ripple in the output torque, which is called commutation torque ripple.Brushless DC motor drives suffer from commutation torque ripple, affecting the performance of the motor in practical applications. A discrete-time switched controller is proposed to reduce the commutation torque ripple in brushless DC motor drives. The proposed controller is a combination of two distinct controllers designed for two different working regions of brushless DC motors. In addition, the commutation delay is also considered in the controller and a predictive structure is implemented to reduce this effect. The overall control scheme consisted of the switched controller and the commutation delay compensation, showing the originality of this study. The performance of the proposed controller scheme is tested through various comprehensive experiments to illustrate its effectiveness and viability.
