and is illustrated in the following figure.
The variables used in the preceding figure and equations correspond to the block variables as shown in the following table:
|Equation Variables||Block Variables|
The inputs to this block are the direct axis (
Alpha) and the
quadrature axis (
Beta) components of the transformed signal and the phase
Angle) between the stationary and rotating frames.
The outputs are the direct axis (
Ds) and quadrature axis
Qs) components of the transformed signal in the rotating frame.
The instantaneous inputs are defined by the following equations:

TI C28x (ISO) Code Replacement
The implementation of this block does not call the corresponding Texas Instruments library function during code generation. The TI function uses a global Q setting and the MathWorks® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
