Decoupled Transform (Six-Phase)
Implement abc and xyz to dqz1z2o1o2 transform
Simscape / Electrical / Control / Mathematical Transforms
The Decoupled Transform (Six-Phase) block converts the time-domain components of a six-phase system in abc and xyz reference frames to direct, quadrature, z1, z2, o1, and o2 components in a rotating reference frame. The three-phase systems abc and xyz are spatially shifted by 30 electrical degrees.
You can configure the block to align the phase a-axis of the six-phase system to either the d-axis or q-axis of the rotating reference frame at time t = 0.
θ = ωt + Offset is the angle between the a and q axes for the q-axis alignment or the angle between the a and d axes for the d-axis alignment, where:
ω is the rotational speed of the rotational reference frame.
t is the time, in s, from the initial alignment.
The Decoupled Transform (Six-Phase) block implements the transform as
abc — a-, b-, and
Components of the three-phase system in an abc reference frame, specified as a vector.
xyz — x-, y-, and z-phase components
Components of the three-phase system in an xyz reference frame, specified as a vector.
θelec — Rotational angle
Angular position of the rotating reference frame, specified as a scalar.
dqz1z2o1o2 — Direct, Quadrature, z1,
Direct, quadrature, z1-, z2-, o1-, and o2-axis components of the system in the rotating reference frame, returned as a vector.
Phase-a axis alignment — dqz1z2o1o2 reference frame alignment
Q-axis (default) |
Whether to align the a-phase vector of the abc reference frame to the d-axis or q-axis of the rotating reference frame.
