Inverse Park Transformation Block

Inverse Park Transformation Block

Description

This block performs the inverse of a Park Transformation to a vector in dq coordinates, outputting the corresponding vector in alpha-beta coordinates

##Parameters and ports

Parameters

No parameters.

###Inputs

• x_d: Component d of the vector in dq coordinates to be transformed.
• x_q: Component q of the vector in dq coordinates to be transformed.
• theta_e: Electrical rotor angle.

###Outputs

• x_alpha: Component alpha of the transformed vector in alpha-beta coordinates.
• x_beta: Component beta of the transformed vector in alpha-beta 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 the "Inverse Park transformation" as the operation that transforms a vector in dq coordinates directly to abc coordinates. Wikipedia, for example.
