clarkeinv − Inverse Clarke transform
|
loadrt clarkeinv [count=N|names=name1[,name2...]] |
The inverse Clarke transform can be used rotate a vector quantity and then translate it from Cartesian coordinate system to a three phase system (three components 120 degrees apart).
clarkeinv.N (requires a floating-point thread)
clarkeinv.N.x
float in
clarkeinv.N.y float in
cartesian components of input
clarkeinv.N.h float in
homopolar component of input (usually zero)
clarkeinv.N.theta float in
rotation angle: 0.00 to 1.00 = 0 to 360 degrees
clarkeinv.N.a
float out
clarkeinv.N.b float out
clarkeinv.N.c float out
three phase output vector
clarke2 and clarke3 for the forward transform.
