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 control, 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 paper dataset can be seen as the author has includedperformance 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.There is related dataset "100W BLDC Sensorless FOC - Sliding Mode vs Flux Observer" ,DOI: https://dx.doi.org/10.21227/8rz1-p666These BLDC motors and controllers are used in many industries including medical e.g. in Positive Airway Pressure respirators,ventilator. There are many research papers, some papers are contradictory with one another, so this study comes in handy to decide.

本数据集用于支撑即将提交至《IEEE电力电子学报》（IEEE Transactions on Power Electronics）的研究论文。在本文及本数据集中，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——实现无刷直流电机（Brushless DC Motor, BLDC）的转速与位置估算。本研究采用的矢量控制方案为行业通用成熟方案，可参考相关专业教科书，仅在转速估算环节引入了滑模观测器（Sliding Mode Observer, SMO）或磁链观测器作为“自适应控制器”。三相逆变器的开关调制策略采用空间矢量调制（Space Vector Modulation, SVM）实现。本论文及数据集的特色在于，作者纳入了滑模观测器与磁链观测器的性能对比，并采用了PWM补偿闭环控制方案。以上所有内容均基于32位实时微控制器实现。本数据集未提及的引脚用于通用控制器局域网（Controller Area Network, CAN）、通用串行总线（Universal Serial Bus, USB）、RS485等外设接口。本次仿真未纳入功率因数校正（Power Factor Correction, PFC）模块，因假设功率因数PF=1。相关数据集为《100W BLDC无传感器磁场定向控制——滑模观测器与磁链观测器对比》，DOI：https://dx.doi.org/10.21227/8rz1-p666。此类无刷直流电机及其控制器可应用于多个工业领域，包括医疗领域，例如持续气道正压通气（Positive Airway Pressure, PAP）呼吸机、医用呼吸机。目前已有大量相关研究论文，部分结论甚至相互矛盾，因此本研究可为相关决策提供可靠参考依据。
