Abstract In electric vehicles (EVs), the major role of BLDC motor is controlling the speed of a vehicle and effective breaking. This can be achieved by reducing the torque and managing the current flow in the motor. In recent researches, current-controlling methods in BLDC give the better way in controlling the speed of a motor. This research work focuses on the design of the speed control system. In this, EV is run by the battery connected with the photovoltaic (PV) system. The proposed work optimally controls the switching devices to manage power for BLDC motor. This extracts the properties of PV system with feedback signals of the bidirectional converter and motor terminals to evaluate the energy transfer level to EV. This can also reduce the decaying effect of battery, which is connected parallel to the converter. Since the proposed controller truncates the error signal with varying angle of vector quadrant named as Truncated Angle Variant (TAV) controller, this can also monitor the accelerator frequency that refers to the required speed of the BLDC motor. The experimental result shows the performance of proposed TAV-based controlling technique and the comparison of parameters with state-of-the-art methods is also made. Graphic abstract

摘要 在电动汽车 (EV) 中，BLDC 电机的主要作用是控制车辆速度和有效制动。这可以通过降低扭矩和管理电机中的电流来实现。在最近的研究中，BLDC 中的电流控制方法为控制电机速度提供了更好的方法。本研究工作的重点是速度控制系统的设计。在这种情况下，EV 由与光伏 (PV) 系统连接的电池运行。所提出的工作以最佳方式控制开关设备以管理 BLDC 电机的电源。这通过双向转换器和电机端子的反馈信号提取 PV 系统的特性，以评估向 EV 的能量传输水平。这也可以减少与转换器并联的电池的衰减效应。由于所提出的控制器通过称为截角变体 (TAV) 控制器的矢量象限的变化角度来截断误差信号，因此这也可以监控指的是 BLDC 电机所需速度的加速器频率。实验结果表明了所提出的基于 TAV 的控制技术的性能，并且还与最先进的方法进行了参数比较。图形摘要
