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, 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 observer isPWMCOmpensCLosed 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. The author has also other 2-3 different complex models, may be uploaded later.

本数据集用于支撑即将投稿至《IEEE Transactions on Power Electronics》的研究论文。在该论文与本数据集中，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）的转速与位置估计。本次采用的矢量控制实现方法为通用经典方法，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（Sliding Mode Observer, SMO）或磁通观测器作为“自适应控制器”。三相逆变器的开关模式采用空间矢量调制实现。本数据集与相关研究的差异化之处在于，作者纳入了基于滑模观测器与磁通观测器的性能对比，并完成了PWM补偿闭环控制。上述所有内容均在32位实时微控制器上实现。未在此处提及的引脚被用于通用控制器局域网（CAN）、通用串行总线（USB）、RS485等其他外设。本次仿真未包含功率因数校正（Power Factor Correction, PFC）模块，因预设功率因数PF=1。本研究关联数据集为“200W无刷直流电机无传感器磁场定向控制——滑模观测器与磁通观测器对比”，DOI：https://dx.doi.org/10.21227/8rz1-p666。此类无刷电机与控制器广泛应用于诸多行业，例如医疗领域的正压通气呼吸器、呼吸机等场景。本研究可为实际工程设计提供决策参考。作者另有2至3套不同的复杂模型，或将在后续上传。
