AC Induction Motor Example
The code was compiled and run on the Texas Instruments TMS320C28x fixed-point DSP device
(IQ_MATH mode) and on the TMS320C3x floating-point DSP device (FLOAT_MATH mode).
The plots of speed and stator current for both devices matched and are shown below.
The plots start from a step change in reference speed from 0.0 to 0.5 and 1024 samples are taken.
The speed eventually settles to the desired reference value and the stator current exhibits a clean
and stable oscillation. The block diagram slide shows at which points in the control system the
plots are taken from.
