This paper presents a design and development of Multi Sector Space Vector Pulse Width Modulation scheme (MS-SVPWM) for the speed control of brushless direct current (BLDC) motor drive. This control scheme is developed to enhance the performance of BLDC under wide range of speed and load variation. The hardware prototype is developed for 400 W, 30 V, 3000 rpm BLDC motor. The drive consists of uncontrolled rectifier unit for providing DC source to inverterunit. The proposed drive control has been done by implementing MS-SVPWM scheme using ANFIS control. The main function of ANFIS controller is to select the suitable sector for the drive and also predict the mismatching pulses by comparing conventional SVPWM and MS-SVPWM switching patterns. This new switching control technique helps to reduce switching losses of inverter and also improves an efficiency of BLDC system. This MS-SVPWM reduces the DC voltage ripple; Total Harmonic Distortion (THD) and torque ripple to the standard level. To verify and validate the practicality of the proposed system, the simulation is first performed using MATLAB Simulink tool. The hardware system is developed for the MS-SVPWM using DSPIC30F4011controller, the simulation and experimental results are presented.

本文提出了一种用于无刷直流（BLDC）电动机驱动器速度控制的多扇区空间矢量脉宽调制方案（MS-SVPWM）的设计和开发。开发该控制方案是为了在各种速度和负载变化范围内增强BLDC的性能。硬件原型针对400 W，30 V，3000 rpm BLDC电机开发。驱动器由不受控制的整流器单元组成，用于为逆变器单元提供直流电源。通过使用ANFIS控制实现MS-SVPWM方案，完成了建议的驱动器控制。ANFIS控制器的主要功能是为驱动器选择合适的扇区，并通过比较传统的SVPWM和MS-SVPWM开关模式来预测失配脉冲。这种新的开关控制技术有助于减少逆变器的开关损耗，还可以提高BLDC系统的效率。该MS-SVPWM降低了直流电压纹波；总谐波失真（THD）和转矩波动达到标准水平。为了验证和验证所提出系统的实用性，首先使用MATLAB Simulink工具进行了仿真。使用DSPIC30F4011控制器为MS-SVPWM开发了硬件系统，并给出了仿真和实验结果。
