Abstract :
This short paper treats one aspect of the identification of state-derivative-coupled systems, such as 
where 
, and 
is invertible. This equation can also be written as 
. We assume that reduced form parameters ( 
) are identifiable and develop a sequence of tests for establishing the identifiability of structural parameters ( 
) from ( 
). The tests are constructive, in that they not only can be used to ascertain the identifiability of ( ); but, if ( ) are not identifiable, can also indicate corrective actions to be taken so that ( ) are identifiable.
