1.88kW BLDC Sensorless FOC - Sliding Mode vs Flux Observer

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, with the addition of SMO or flux observer gives the estimation of speed and the sensorless rotor position. 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 following , with analysis which can be drawn from seeing attached graphs -performance comparison using Sliding Mode Observer (SMO) and flux observerPWM switching frequency is varied 45 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.These 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.There is related dataset, where also 8-pole Y winding motor is used but of different specification - "200W BLDC Sensorless FOC - Sliding Mode vs Flux Observer" ,DOI: https://dx.doi.org/10.21227/8rz1-p666,

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）的研究论文。本文及配套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——实现无刷直流电机（Brushless DC Motor, BLDC）的转速与转子位置估计。本研究采用成熟的矢量控制实现方案，新增滑模观测器（Sliding Mode Observer, SMO）或磁链观测器以完成转速与无传感器转子位置的估计。三相逆变器的开关调制采用空间矢量调制方案。

本数据集与现有研究的差异在于，作者纳入了以下内容，并可通过附带图表开展分析：
1. 滑模观测器与磁链观测器的性能对比；
2. 将PWM开关频率从20 kHz拓展至2 MHz，共设置45组工况，可为MOSFET开关频率的选型提供参考（工业场景中亦有采用20 kHz的案例）；
此外还涵盖：稳定裕度、开环控制性能、传递函数补偿、闭环整定、未补偿系统与补偿系统的根轨迹、幅频与相频波特图（Bode Plot）、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（Nyquist Plot）、未补偿系统与补偿系统的尼科尔斯图（Nichols Chart）、未补偿系统与补偿系统的冲激响应、正弦激励响应；其中补偿系统为引入SMO/磁链观测器后的闭环系统。

所有实验均基于32位实时微控制器完成，未提及引脚分配的引脚用于通用CAN、USB、RS485等外设接口。本仿真未包含功率因数校正（Power Factor Correction, PFC）模块，因假设系统功率因数PF=1。

此类无刷直流电机及其控制器广泛应用于多个行业，包括医疗领域，例如正压气道通气机（呼吸机）中。本研究可为工业实际设计与学术研究提供有效参考。作者已将本研究成果应用于2~3种新型复杂模型的设计（尚未完成），相关内容后续可能上传。另有相关数据集，采用8极Y形绕组电机，但规格不同，题为"200W BLDC Sensorless FOC - Sliding Mode vs Flux Observer"，DOI: https://dx.doi.org/10.21227/8rz1-p666。
