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/IGBTs(as of ST Microelectronics) etc. 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投稿至《IEEE电力电子汇刊》（IEEE Transactions on Power Electronics）的研究论文。在本论文与数据集中，研究人员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——开展无刷直流电机（Brushless DC Motor, BLDC）的转速与位置估算工作。其矢量控制实现方法为通用成熟方案，可参考任意相关教材，仅额外引入了滑模观测器（Sliding Mode Observer, SMO）与磁链观测器（Flux Observer），二者在转速估算环节中充当“自适应控制器”。三相逆变器的开关模式采用空间矢量调制（Space Vector Modulation）方案实现。本论文与数据集的特色在于：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；同时将脉冲宽度调制（Pulse Width Modulation, PWM）开关频率在20 kHz至2 MHz范围内调整了44次，该设置可辅助确定金属氧化物半导体场效应晶体管（Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET）、绝缘栅双极型晶体管（Insulated Gate Bipolar Transistor, IGBT，如意法半导体STMicroelectronics产品）等器件的最优开关频率。本研究涵盖开环传递函数补偿、根轨迹分析、闭环控制与弱磁控制等内容，且所有实现均基于32位实时微控制器完成。本数据集未列明的引脚被用于通用控制器局域网（CAN）、通用串行总线（Universal Serial Bus, 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，因预设功率因数（Power Factor, PF）为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链接：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众多行业，其中医疗领域包括正压气道通气呼吸器、呼吸机等场景。本研究可为工业领域的实际设计工作以及学术研究提供重要参考依据。作者已将本次研究结果用于2-3个尚未完成的复杂模型的设计中，相关内容后续可能会上传。
