Package Modelica.Electrical.Machines.SpacePhasors.BlocksBlocks for space phasor transformation
Package Modelica.Electrical.Machines.SpacePhasors.BlocksThis package contains space phasor transformation blocks for use in controllers:
Space phasors are defined as vectors of length = 2, the first element representing the real part and the second element representing the imaginary part of the space phasor.
Extends from Modelica.Icons.Package (Icon for standard packages).
| Name | Description |
|---|---|
FromPolar | Converts a space phasor from polar coordinates |
FromSpacePhasor | Conversion of space phasors to multi phase instantaneous values |
LessThreshold | Sets angle to zero when length is below threshold |

Block Modelica.Electrical.Machines.SpacePhasors.Blocks.Rotator
Rotates a space phasor (voltage or current) input u by the angle in negative mathematical direction. This block represents the transformation of one space phasor u from one rotating reference (coordinate) frame into another where the space phasor is y. The output reference frame leads the input reference frame by angle angle.
