AbsolutePositionMeasure absolute position vector of the origin of a frame connector |
SystemModel["Modelica.Mechanics.MultiBody.Sensors.AbsolutePosition"]
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The absolute position vector of the origin of frame_a is determined and provided at the output signal connector r.
Via parameter resolveInFrame it is defined, in which frame the position vector is resolved:
resolveInFrame = Types.ResolveInFrameA. | Meaning |
---|---|
world | Resolve vector in world frame |
frame_a | Resolve vector in frame_a |
frame_resolve | Resolve vector in frame_resolve |
If resolveInFrame = Types.ResolveInFrameA.frame_resolve, the conditional connector "frame_resolve" is enabled and r is resolved in the frame, to which frame_resolve is connected. Note, if this connector is enabled, it must be connected.
If resolveInFrame = Types.ResolveInFrameA.frame_a, the output vector is computed as:
r = MultiBody.Frames.resolve2(frame_a.R, frame_b.r_0);
