addOpening
Add signal to list of openings for slLinearizer or slTuner interface
Syntax
addOpening(s,pt)
addOpening(s,blk,port_num)
addOpening(s,blk,port_num,bus_elem_name)
Description
addOpening(s,pt) adds the specified point (signal) to the list of permanent openings
on page 15-281 for the slLinearizer or slTuner interface, s.
Use permanent openings to isolate a specific model component for the purposes of
linearization and tuning. Suppose you have a large-scale model capturing aircraft
dynamics and you want to perform linear analysis on the airframe only. You can use
permanent openings to exclude all other components of the model. Another example is
when you have cascaded loops within your model and you want to analyze a specific loop.
addOpening(s,blk,port_num) adds the signal at the specified output port of the
specified block as a permanent opening for s.
addOpening(s,blk,port_num,bus_elem_name) adds the specified bus element as a
permanent opening.
Examples
Add Opening Using Signal Name
Suppose you want to analyze only the inner-loop dynamics of the scdcascade model.
Add the outer-loop feedback signal, y1m, as a permanent opening of an slLinearizer
interface.
