1.88kW BLDC Sensorless FOC with Adaptive Sliding Mode Observer

This dataset is in support of my planned research paper shortly to be 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. The switching frequency for these controllers is generally 20 kHz or more.In this dataset, switching frequency has been increased from 20 kHz to 1MHZ , at 26 different PWM frequencies and the comparison of the resulting characteristics are drawn.BLDC motors ae used in medical industry ,ventillators, solar trackers, CNC servodrives, industrial robots, automative, electric vehicles- autos, rickshaws etc.Using this dataset, any 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.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 26 times from 20 kHz to 1 MHz , - will help decide MOSFETs switching frequency.Of course, the Rdson, dc link inverter voltage ,other practical parameters etc has been taken into consideration (not submitted here) bu some analysis related to it,you may find in the authors Transaction paper.Separate results at all these 26 frequenciesStability Margins - Gain/PhaseOpen Loop Control PerformanceTransfer Function CompensationClosed loop TuningRoot Locus of Uncompensated System and Compensated SystemBode Plot - magnitude and phasePole Zero Map of Uncompensated System and Compensated SystemUnit-Step Response of Uncompensated System and Compensated SystemNyquist plot of Uncompensated System and Compensated SystemNichols chart of Uncompensated System and Compensated SystemImpulse Response of Uncompensated System and Compensated SystemSinusoidal ExcitationAll this is implemented on 32-bit Real-Time microcontroller.
