“…Then, the rotor's position and speed are calculated from mathematical relations. For instance, in [25], for a given BLDC motor, the voltages values of and have been estimated using a second-order SMO, and the rotor position is obtained from = 2 − tan −1 ( ) (12) and to calculate of the rotor's speed, and to calculate the speed of rotor, the derivative of position of rotor has to be determined. Derivation may lead to significant computational error due to switching noises.…”

Nowadays, due to excellent advantages of permanent magnet brushless (PMBL) motors such as high efficiency and high torque/power density, they are used in many industrial and variable-speed electrical drives applications. If the fabricated PMBL motor has neither ideal sinusoidal nor ideal trapezoidal back-EMF voltages, it is named nonideal (or nonsinusoidal) PMBL motor. Employing conventional control strategies of PMSMs and BLDCMs lowers the efficiency and leads to unwanted torque ripple, vibration, and acoustic noises. Moreover, in many applications to reduce the cost and enhance the reliability of drive, sensorless control techniques are used. This paper proposes a novel sensorless control for a nonsinusoidal PMBL motor with minimum torque ripple. To develop smooth torque, the selected torque harmonic elimination strategy is employed. Furthermore, to estimate the rotor position and speed, a novel full-order sliding mode observer is designed. Proposed observer estimates the position and speed of motor from standstill to final speed. The proposed observer is robust to uncertainty of harmonic contents in phase back-EMF voltage and able to run the motor from standstill with closed-loop control scheme. The capabilities of torque ripple minimization and sensorless strategies are demonstrated with some simulations.

“…The schematic of the DTC BLDC motor drive is shown in Fig.1. In the stationary reference frame, the stator flux linkage can be obtained by sampling the stator phase voltages and currents, like formula (4) and(5), the rotor flux linkage can be derivate according to formula (2) and (3). The magnitude and phase angle of stator flux linkage vector can be calculated from formula (6) and 7.…”

The design requirements of brushless DC (BLDC) motor control system are on the increase high with the continuously broaden application fields of it. This paper presents the direct torque control(DTC) drive scheme for BLDC motor. The rationale of DTC for BLDC motor is analyzed and torque error is directly used to control the inverter states. The magnitude and phase angle of stator flux linkage vector are deduced under the α-β axis stationary reference frame. The control algorithm of stator flux linkage and torque is hysteresis control, then the results and flux linkage regulate the inverter. MATLAB simulation results indicate that DTC scheme for BLDC motor has faster speed of torque response and better performance, achieve the purpose.

Esse trabalho apresenta uma metodologia de projeto para os ganhos de um observador de força contra-eletromotriz (FCEM) para a máquina BLDC. Devido a característica não-senoidal da máquina BLDC, a transformação de Park convencional pode gerar oscilações de torque quando se utiliza controle vetorial clássico. Assim, a informação da FCEM é essencial para implementação de técnicas de controle vetorial estendido e adicionalmente implementação de algoritmos de estimação da velocidade e posição rotórica. Os ganhos do observador são projetados utilizando a técnica de alocação de polos e as limitações do observador em tempo discreto são avaliadas. Uma comparação com um observador de Luenberger é apresentada. Resultados de simulação e experimentais corroboram a metodologia proposta, demonstrando a robustez do observador.
