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 included ollowing , with analysis which can be drawn from seeing attached graphsperformance 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.

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》（IEEE电力电子汇刊）的计划研究论文。本论文与数据集针对无刷直流电机（BLDC, Brushless DC Motor）的转速与位置估算展开研究，采用无传感器矢量控制方法，即磁场定向控制（FOC, Field Oriented Control）与观测器方案。其实现方法采用通用的矢量控制方案，可参考任意相关教材，额外引入滑模观测器（SMO, Sliding Mode Observer）或磁链观测器作为转速估算环节的自适应控制器。本方案采用空间矢量调制实现三相逆变器的开关模式。本论文与数据集的特色在于纳入以下内容，并可通过附随图表展开分析：滑模观测器与磁链观测器的性能对比；PWM开关频率在20 kHz至2 MHz范围内设置44个梯度值，可用于辅助确定MOSFET的最优开关频率（工业场景中亦常采用20 kHz作为开关频率）；稳定裕度分析；开环整定；传递函数补偿；闭环控制；弱磁控制；未补偿系统与补偿系统的根轨迹；波特图（含幅频与相频特性）；未补偿系统与补偿系统的零极点分布图；未补偿系统与补偿系统的单位阶跃响应；未补偿系统与补偿系统的奈奎斯特图；未补偿系统与补偿系统的尼科尔斯图；未补偿系统与补偿系统的冲激响应；上述补偿系统均基于滑模观测器/磁链观测器构建。所有实验均基于32位实时微控制器完成，本数据集未提及的引脚用于通用CAN、USB、RS485等外设接口。本仿真未纳入功率因数校正（PFC, Power Factor Correction）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》（"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其控制器广泛应用于多个工业领域，包括医疗行业，例如持续气道正压通气呼吸器、呼吸机等场景。本研究可为工业实际设计与学术研究提供参考依据。作者已基于本研究结果构建了2~3套不同的复杂模型（尚未完成），后续或将公开上传。
