1.88kW BLDC Sensorless FOC - Sliding Mode vs Flux Observer with FW

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 observerPWM switching frequency is varied 44 times from 20 kHz to 2 MHz , - will help decide MOSFETs switching frequency.Open LooTransfer Function CompensationRoot Loci,Closed loopField WeakeningAll 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 "200W BLDC Sensorless FOC - Sliding Mode vs Flux Observer" ,DOI: https://dx.doi.org/10.21227/8rz1-p666These brushless motors and controllers are used in many industries including medical e.g. in Positive Airway Pressure respirators,ventilator.This study comes in handy to decide when designing in practice for industries and also for academia purposes. The author has used these results in designing new 2-3 different complex models(incomplete), may be uploaded later.

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。在本论文及配套数据集中，我们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）的转速与位置估计。本次所采用的矢量控制实现方法为通用经典方案，可参考各类专业教材，仅在转速估计环节加入了滑模观测器（Sliding Mode Observer，SMO）或磁链观测器作为自适应控制器。三相逆变器的开关模式采用空间矢量调制实现。
本数据集与配套论文的特色之处在于：作者纳入了基于滑模观测器与磁链观测器的性能对比实验；将脉冲宽度调制（Pulse Width Modulation，PWM）开关频率在20 kHz至2 MHz范围内进行了44次梯度调整，该实验结果可辅助确定金属氧化物半导体场效应晶体管（MOSFET）的最优开关频率；同时涵盖开环传递函数补偿、根轨迹分析、闭环控制以及弱磁控制等内容。
所有实验均基于32位实时微控制器完成。本方案未提及的引脚将用于通用控制器局域网（CAN）、通用串行总线（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，因预设功率因数PF=1。
本研究另有配套数据集《200W BLDC Sensorless FOC - Sliding Mode vs Flux Observer》，DOI：https://dx.doi.org/10.21227/8rz1-p666。
此类无刷直流电机及控制器广泛应用于多个工业领域，其中医疗领域包括持续气道正压通气呼吸器、呼吸机等设备。本研究成果可用于工业实际设计选型以及学术研究参考。作者已将本次实验结果用于2-3个全新复杂模型的开发（目前尚未完成），相关内容后续可能会公开上传。
