      APL AND GRAPH THEORY IN DYNAMIC SYSTEMS ANALYSIS. 

      Schizas, Christos N.; Evans, F. J. (1981)
      It is demonstrated how well-established graph theoretic results can be exploited in the analysis of large-scale systems, and directed towards questions of design such as controllability and stability. The generalized nature ...

      CONTROL SYSTEM DESIGN USING GRAPHICAL DECOMPOSITION TECHNIQUES. 

      Evans, F. J.; Schizas, Christos N.; Chan, J. (1981)
      If system state-space 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 ...

      Digraph analysis of large-scale 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 ...

      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 ...

      Rank-invariant transformations and controllability of large-scale systems 

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

      The structural aspects of pole assignment 

      Evans, F. J.; Schizas, Christos N. (1981)
      The ability to assign the poles of a mult.ivur-inble 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. ...
