Article
APL AND GRAPH THEORY IN DYNAMIC SYSTEMS ANALYSIS.
Schizas, Christos N.; Evans, F. J. (1981)It is demonstrated how wellestablished graph theoretic results can be exploited in the analysis of largescale systems, and directed towards questions of design such as controllability and stability. The generalized nature ...

Article
CONTROL SYSTEM DESIGN USING GRAPHICAL DECOMPOSITION TECHNIQUES.
Evans, F. J.; Schizas, Christos N.; Chan, J. (1981)If system statespace equations are mapped into a digraph, the algorithmic decomposition into connected subsystems, together with the application of sensitivity analysis, provides an alternative approach to quasioptimization ...

Article
Digraph analysis of largescale systems: The system primitive
Evans, F. J.; Schizas, Christos N. (1979)Mapping differential equations into digraphs is shown to give additional insight into system properties, such as controllability and observability. The concept of the system primitive is introduced. © 1979, The Institution ...

Article
A graph theoretic approach to multivariable control system design
Schizas, Christos N.; Evans, F. J. (1981)A graph theoretic approach is described for the design of multivariable control for large systems as an alternative to geometric methods. An example is given f⊙r a distillation column to demonstrate the technique, with a ...

Article
Rankinvariant transformations and controllability of largescale systems
Schizas, Christos N.; Evans, F. J. (1980)The relevance of structure to the exact determination of rank in largescale systems is discussed, with particular reference to state transformations and the conditions for controllability (observability). The structural ...

Article
The structural aspects of pole assignment
Evans, F. J.; Schizas, Christos N. (1981)The ability to assign the poles of a mult.ivurinble system, even under an imposed set of constraints (e.g. decentralized control) is shown to reside completely in structural properties made explicit in the system digraph. ...
