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 MHzOpen LoopTransfer Function CompensationRoot Loci,Closed 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 "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投稿至《IEEE电力电子学报》（IEEE Transactions on Power Electronics）的研究论文。本论文及本数据集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（BLDC）电机的转速与位置估算。其实现方法采用成熟的矢量控制方案，可参考任意相关教材，仅额外引入滑模观测器（Sliding Mode Observer, SMO）或磁链观测器作为转速估算环节的自适应控制器。三相逆变器的开关模式采用空间矢量调制技术实现。本论文与数据集的特色之处在于：作者纳入了滑模观测器与磁链观测器的性能对比实验；将PWM开关频率从20 kHz至2 MHz共设置44组变化工况；覆盖开环、传递函数补偿、根轨迹以及闭环等多种研究场景。所有实验均基于32位实时微控制器完成。本文未提及的引脚被用于通用CAN总线、USB、RS485等其他外设接口。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《200W无刷直流电机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控制器广泛应用于多个行业，医疗领域例如正压气道通气呼吸器、呼吸机等。本研究可为工业界实际工程设计以及学术研究提供重要参考依据。作者已利用本次实验结果开展2至3种不同复杂模型的设计工作（目前尚未完成），相关内容后续或可公开上传。
