Summary
Microchip’s AC Induction Motor (ACIM) vector control solution
is written for the dsPIC30F/33F family of devices. The
software makes extensive use of dsPIC30F/33F peripherals
for motor control. The software implements vector control
of an ACIM, using the indirect flux control method. The
program is written in C and has been specifically optimized
and well annotated for ease of understanding and program
modification.
