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 Transactions on Power Electronics"的研究论文。在本论文及数据集中，无刷直流电机（BLDC）的转速与位置估计采用无传感器矢量控制方法实现，即磁场定向控制（FOC）与观测器。本研究采用的矢量控制方案为通用成熟方法，可参考各类相关教材，仅在转速估计环节加入了滑模观测器（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通过空间矢量调制实现。本数据集与相关研究的差异之处在于：作者纳入了基于滑模观测器（SMO）与磁链观测器的性能对比；将PWM开关频率从20 kHz至2 MHz共调整44次，可为MOSFET开关频率的选型提供参考。本研究涵盖开环传递函数补偿、根轨迹、闭环控制以及弱磁控制等内容，所有实验均在32位实时微控制器上完成。本文未提及的引脚被用于通用CAN、USB、RS485等外设接口。由于假定功率因数（PF）为1，故本仿真未纳入功率因数校正（PFC）模块。本研究关联的数据集为"200W BLDC无传感器FOC——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，例如医疗领域的正压气道通气呼吸器、呼吸机等设备。本研究结果可为工业实际设计以及学术研究提供参考依据。作者已将本次研究结果用于构建2-3个全新的复杂模型（尚未完成），相关内容后续可能会上传。
