                                                                         Caution

Though the uploaded data  and values are true,designed for the real practical scenarios only, technical familiarity is a must as it involves risks associated with handling high voltages, motors, electrical shock, fire hazard , personal injury and/or property damage etc. The author is not responsible if the algorithm is misunderstood or all this is copied without understanding or improperly implemented and mishappening due to it.  If used in vehicle like bus, car or cart or bike or drones, unmanned aerial vehicles or unmanned combat aerial vehicle, these values though analyzed but still do not guarantee anything and may cause accident if throttle or pedal or brake improperly looped etc. The author is not responsible if the copied values cause mishappening.

Dataport Scripts

These scripts are given to see the x-axis and y-axis used. The axes in different datasets are different.  In some , axes are cartesian,polar,s-plane,z-plane, logarithmic, or linear.  Make sure,axes are correct,otherwise you will get different or incorrect  or wrong results. (open scripts to see what the actual axes are in each dataset.)

1)  The scripts are functions in .txt. These scripts are related only with dataset (not of complete experiment).

2) Only one script is given, it is same for the all the experiments carried out.

3) As these are functions, these can be used at many places and even reveals what is in the dataset and the graph.

4) Only axis related part is given.

5) Authors IEEE CodeOcean capsule can be referred for more details.

 The axis of following is given in Scripts.zip

• smo_BodePlot
• foc_BodePlot
• smo_PoleZeroMap
• foc_PoleZeroMap
• smo_UnitStep
• smo_Impulse
• foc_UnitStep
• foc_Impulse

 (3) The zip folders from 15 to 2000 are 15 kHz to 2000 kHz (2MHz) and are named according to frequency . On these 33 frequencies these experiments are repeated.

 (4)  Each of the zip folders has 18 datasets in .mat

1. Torque
2. Power
3. Id
4. Iq
5. smo_BodePlot
6. smo_RootLocus
7. smo_PoleZeroMap
8. smo_NyquistPlot

(5)  The datasets - Torque, Power, Id, Iq are speed characteristics.

(6) The datasets -  smo_BodePlot,  smo_RootLocus,  smo_PoleZeroMap,  smo_NyquistPlot, smo_NicholsChart are control characteristics for field oriented control with sliding mode observer.

(7)  The datasets - smo_UnitStep, smo_Impulse  are  system response for field oriented control with sliding mode observer.

(8) The datasets - foc_RootLocus, foc_PoleZeroMap, foc_NyquistPlot, foc_NicholsChart are control characteristics without sliding mode observer.

(10) frequency.csv is the list of PWM switching frequencies.

(11)  adc.csv, pwm.csv,hrpwm.csv, dutycycle.csv, inverter_deadband.csv  are on  used microcontroller TMS320F28388D.

(12) pwm.csv and hrpwm.csv has switching frequecy vs resolution in bits and %.

(13) dutycycle.csv is switching frequecy vs minimum and maximum duty  cycle in %.

(14) inverter_deadband.csv is dead band delay time of 3 phase inverter MOSFET in μs.

How use Dataset Files

The data can be studied and used in various ways.

(1) The values given in the dataset or in the Research paper can be used for different prototypes designing.

(2) How the motor control will vary at these frequencies,   in hand ready many values of Kp, Ki, are given. It is very important, as it takes months for an engineer and save engineer costs. The exact value is in the research paper. Here is data.

(3) Put these values in the software code and use circuit as desired. Make sure you have read Caution .

(4)  As the dataset and Research paper has more than 1 value where satisfactory performance is achieved, more than 1 industry or design can use these values and implement in practice.

(5) The satisfactory performance can be obtained using one value or other by using less engineering knowledge or with open-source softwares.

(6)  There are many data analysis softwares - proprietary and open source softwares.

(7)  The dataset can be loaded into proprietary softwares or trial versions of Finite element or other simulation softwares to regenerate same model  or other model or to conduct other study.

(8) For finer analysis, the dataset can be used to see details at much shorter interval.

(9)   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.

(10)  One particular frequency or some frequencies can be copied for degree thesis, project or phd thesis.
