1.88kW BLDC Sensorless FOC - Sliding Mode vs Flux Observer

This dataset is in support of my planned research paper shortly to be submitted to "IEEE Transactions on Power Electronics".In this paper and dataset, speed and the position estimation of BLDC is done using the sensorless vector control method i.e., Field Oriented control (FOC) and observer. The implementation method is the known method of vector contro, so any textbook can be referred, with the addition of SMO or flux observer which acts as the "Adaptive Controller" in the estimation of speed. The switching pattern of the 3-phase inverter is implemented using space vector modulation. DIfferences in this dataset can be seen asperformance comparison using Sliding Mode Observer (SMO) and flux observer isPWMCOmpensCLosed loopAll this is implemented on 32-bit Real-Time microcontroller. The pins usage not mentioned here are used for other General-Purpose-CAN,USB, RS485 etc.PFC is not included in this simulation as it is assumed that PF = 1.本数据集用于支撑即将提交至《IEEE电力电子汇刊》（IEEE Transactions on Power Electronics）的研究论文。在本论文及配套数据集中，采用无传感器矢量控制方法——即磁场定向控制（Field Oriented Control, FOC）与观测器——完成无刷直流电机（BLDC）的转速与位置估计。所采用的实现方案为成熟的矢量控制方法，可参考任意相关教科书，仅在转速估计环节新增了滑模观测器（Sliding Mode Observer, SMO）或磁链观测器作为"自适应控制器"。三相逆变器的开关模式采用空间矢量调制实现。本数据集的差异体现为：采用滑模观测器与磁链观测器开展性能对比，涵盖脉宽调制（Pulse Width Modulation, PWM）补偿与闭环控制等内容。所有实验均基于32位实时微控制器完成。本说明未提及的引脚用于连接通用CAN、USB、RS485等外设。本次仿真未包含功率因数校正（Power Factor Correction, PFC）模块，因假设功率因数PF=1。
