PWPM algorithm was made
to drive AC motors optimally
minimizing harmonics loss and
it has its own representation in
generalized phase-space which
might be visually interesting for
promtp estimation of efficiency.
PWPM algorithm is available on www.andrijar.com/pwm/index.php.
It is 3D: click it with
mice to rotate and
roll the middle button
to zoom, press it to
move around.
