On the multilevel structure of large-scale composite systems
Ümi̇t Özgüner, Will Perkins · IEEE Transactions on Circuits and Systems · 1975
Existence of the solution to the composite state space representation for large-scale composite (LSC) systems is discussed for a specified multilevel structure. It is shown that the multilevel structure causes the existence condition to be decomposed so each constituent in the structure is considered separately. The LSC system is represented by a digraph and an algorithm using graph theory to identify the constituents of the multilevel structure is given.
