Park Transformation Block

Park Transformation Block

Description

This block performs a Park Transformation to a vector in ABC coordinates, outputting the corresponding vector in dq coordinates

##Parameters and ports

Parameters

No parameters.

###Inputs

• x_alpha: Component 'alpha' of the vector in alpha beta coordinates to be transformed.
• x_beta: Component 'beta' of the vector in alpha beta coordinates to be transformed.
• theta_e: Electrical rotor angle.

###Outputs

• x_d: Component d of the transformed vector in dq coordinates.
• x_q: Component q of the transformed vector in dq coordinates.

Examples

Example 1

This example demonstrates how to use the Clarke and Park transformations and their inverses. The simulation compares the behavior of the standard electrical model of the BLDC with the dq electrical model (using the correct transformations for comparison)

##Additional Information Some sources cite "Park transformation" as the operation that transforms a vector in abc coordinates directly to dq coordinates. Wikipedia, for example.
