1.88kW BLDC Sensorless FOC with Adaptive Sliding Mode Observer

This dataset is on the study of Motor controllers, for which author has done numerous experiments, and the analysis along with these will also be shortly submitted to "IEEE Transactions on Power Electronics".The results contained in this dataset are graphs which give intutive idea on the control characteristics, whether the pole/zero is on the imaginary axis or the right half plane. Still in today's practice, the switching frequency for these controllers are used even 20 kHz or more, whereas MOSFETs can be switched to 2 MHz.BLDC motors ae used in medical industry ,ventillators, solar trackers, CNC servodrives, industrial robots, automative, electric vehicles- autos, rickshaws etc.Using this dataset, the industrial engineer can decide whether to run at that frequency or not. So, this study comes in handy to decide when designing in practice for industries and also for academia purposes.In this particular dataset, MOSFET is switched from 20 kHz to 2MHZ , at 46 different PWM frequencies and the resulting characteristics.The author has also used these results in designing new 2-3 different complex models (incomplete), may be uploaded later. There are related datasets submitted to IEEE-Dataport and also to the Transaction Papers. So, the instructions and abstract is almost similar in all of these datasets.The speed and the position estimation of BLDC is done using the sensorless vector control method i.e., Field Oriented control (FOC) with the addition of SMO observer which 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) at different frequencies.PWM switching frequency is varied 46 times from 20 kHz to 2 MHz , - will help decide MOSFETs switching frequency.
