Detailed Description
Methods to compute natural projections that exhibit the observer property.
Methods to compute natural projections that exhibit the obsrver property.
The observer algorithm is elaborated in K. C. Wong and W. M. Wonham, "On the Computation of Observers in Discrete Event Systems," Discrete Event Dynamic Systems, vol. 14, no. 1, pp. 55-107, 2004. In addition, methods to compute natural projections that exhibit output control consistency (OCC) and local control consistency (LCC) are provided. See for example K. Schmidt and C. Breindl, "On Maximal Permissiveness of Hierarchical and Modular Supervisory Control Approaches for Discrete Event Systems," Workshop on Discrete Event Systems, 2008. Furthermore, an algorithm for computing natural observers without changing event labels as presented in Lei Feng; Wonham, W.M., "On the Computation of Natural Observers in Discrete-Event Systems," Decision and Control, 2006 45th IEEE Conference on , vol., no., pp.428-433, 13-15 Dec. 2006 is implemented.
