I have some problems with the Simscape Block "Park to Clarke Angle Transform".
in the helb ther ist the same Matrix that I normaly use:
[alpha = [ cos(phi) -sin(phi) * [ d
betta ] sin(phi) cos(phi) ] q]
if I look under the Mask in the function blocks there ist:
[alpha = [ cos(offset-phi) +sin(offset-phi) * [ d
betta ] -sin(offset-phi) cos(offset-phi) ] q]
I use the a-axis to d-axis aligen.
So what ist the reasen for this change and why my controller only work with the Matlab Matrix?
Thanks Andy

In this block 'offset' can be either 0 for D-axis alignment or pi/2 for Q-axis alignment. If a-axis is aligned with d-axis, offset=0 and the two matrices are equal. That is because sin(-phi)=-sin(phi) and cos(-phi)=cos(phi).
