This is a software part of my engineering thesis. I started working on it in the middle of December 2015. Later I defended my engineering thesis somewhere on March 2016 with final grade of good plus.
This software basically:
- Computes discrete Fourier transform (aka DFT) of input signal by using fast Fourier transform (aka FFT) algorithm
- Computes root mean square (aka RMS) of input signal
- Displays frequency domain of input signal
ALL IN REAL TIME!
Here special thanks MUST go to Tilen Majerle.
I used his libs and also was peeking at his code to make my FOURIER
working
on STM32F429I-DISCO
!
This software was battle tested with i.a.:
- main theme of "The Good the Bad and the Ugly" movie - DEMO HERE
- 3,3 kW three phase induction motor
Subject: Project of monitoring system of electric drive using microcontroller STM32F429I-DISCO
Abstract: The thesis deals with diagnostics and monitoring of electric drive. A description of designed and built electric drive monitoring system is presented. Line currents are measured by three Hall effect transducers. The microcontroller's software processes an input signal and displays results on the controller's LCD screen. The designed system's functioning is verified by a professional diagnostic system. A review of induction motor diagnostic methods and monitoring systems is given as well.
