Variable frequency drives (VFDs) have been used for position sensors for many years. Alternatively, reliable VFDs for smart autonomous systems require the simultaneous configuration of sensors and sensorless operation. This paper details the design and implementation of a continuous fast terminal (CFT) sliding mode controller (SMC) based speed controller and speed estimation through the CFT sliding mode observer (SMO) that accounts for iron loss while calculating total disturbances. The rotor speed dynamics of the PM brushless DC motor (PMBLDCM) drive system is first investigated considering lumped disruption (interference, parametric complexity, and non-linear dynamics). The built-in SMC can control the rotor speed in real time, as well as analyze and compensate for aggregated interruptions in rotor speed dynamics. Additionally, the field-oriented control (FOC) method is developed to maximize torque production while drastically minimizing torque ripples. With this approach, the zero torque pulsation constraint is gradually achieved at a wide speed range. The validation of the proposed CFT-SMC with FOC is carried out using simulation and experiments. According to the comparative study, the proposed sensorless control outperforms conventional methods due to the inclusion of iron loss.

INTRODUCTIONLow-powered Electric vehicles and high precision industrial applications benefit from permanent magnet brushless DC motors (PMBLDCM) [1]. In addition to improving the torquespeed characteristics, the application would also increase the torque-weight ratio, improve control sensitivity, and reduce vibration. As a result of magnetic alignment and winding configuration, PMBLDC is characterized by a trapezoidal back electromagnetic force (EMF), which demands a specific control strategy to maintain the electromagnetic torque. Normally, PMBLDCM works in a six-step conduction mode, Manuscript

“…However, phase delay errors and errors associated with the rotor position detection result in undesired torque pulsations [8][9][10]. Thus, considerable efforts have been exerted to improve the performance of BLDC motor drives: by compensating for the commutation error [8][9][10][11][12][13][14]; by Hall sensor adjustment methods [15,16], and the utilization of a single sensor [17]; by minimizing the torque ripple [18][19][20][21][22][23]; or through the development of high-speed sensorless BLDC drives [24][25][26][27].…”

The control techniques of the brushless DC (BLDC) motor have gained a large amount of interest in recent years, with their use being implemented in order to achieve a high-performance drive, including quick transient response and high-quality waveforms at the steady state. This paper provides a comparative study between three control schemes of BLDC motors: the direct power control scheme using a finite control set model predictive control (FCS-MPC) approach, the stator current controlled scheme using an FCS-MPC approach, and the stator current controlled scheme using ON–OFF hysteresis current controllers. The three systems were studied and investigated under the same operating conditions. The comparative study included investigating the performance of the BLDC drive in both steady state and transient operations. Qualitative and quantitative analyses were performed on the results obtained with each control scheme. The obtained results demonstrate the validity and effectiveness of the three investigated schemes in controlling the motor speed to the desired value under sudden load changes and achieving satisfactory quick transient responses. However, the results indicate the superiority of the direct power control scheme using an FCS-MPC approach over the others in terms of its minimum torque ripple, lowest torque and speed pulsations, minimum active and reactive power ripples, and high-quality waveforms of the stator currents drawn by the motor with minimum THD.

SummaryAt present taking into account the situation of the environment and the growing demand of fossil fuels, electric vehicles (EVs) are a highly promising option for the transportation system. Many manufacturers of electric vehicles employ BLDC motors as the vehicle's driving component. In contrast to the many advantages that BLDC motors offer, one of the major drawbacks of employing these motors is the production of relatively high distortion in electromagnetic torque that is created by commutation. This distortion in torque has an effect on the vehicle's performance. In this proposed work a BLDC motor is powered by a cutting‐edge, highly gained q‐ZSI Ultra‐Extended Boost Active Switch Controlled Based Quasi Z‐source Inverter, or UEBASC‐qZSI. In the aforementioned drive, the torque distortion is minimized with the use of a modified direct torque control approach. With the aid of this UEBASC‐qZSI, the efficiency of EVs can be improved, and the overall safety of the driving cycle is also increased. Any vehicle's efficiency can be enhanced with the help of this UEBASC‐qZSI, and the overall safety of the overall system can also be improved. To validate the efficacy of the system, a Simulink model is developed in the MATLAB platform. Also, a hardware prototype model is developed for experimental authentication. The modeling and investigational findings demonstrate that the proposed system has significantly reduced the torque ripple while obtaining the necessary input dc bus voltage.
