A numerical-substructure-based framework for the synthesis of substructured dynamics, substructurability, and exact synchronisation controllers using state-space methods is presented in this paper. Substructurability is used to analyse the dynamic properties of numerical substructures and transfer systems, on the basis of controllability, substructured eigenvalue, and condition number techniques. Exact synchronisation controllers are designed under the assumptions of unknown parameters of the tested components and are used to achieve a higher level of synchronisation over the transient state. Implementation studies present a synchronised-component-based approach for the controller design and also verify that (1) substructured eigenvalues provide a general indicator to predict stability and performance in advance and (2) slow substructured eigenvalues due to low damping or large mass within a numerical substructure tend to yield ineffective and inefficient tests.
