Description

pict

This block transforms a two-dimensional vector [xd xq]   from a rotating reference frame into a vector [yα yβ]   in the stationary reference frame. The first input of the block is the vector [xd xq]  . The second input is the angle φ   between the rotating and the stationary frame. φ   is given in radians.

  yα  =   cosω1t - sin ω1t  ⋅ xd
  yβ      sin ω1t  cosω1t     xq
