Control of Nondeterministic Discrete-Event Systems for Bisimulation Equivalence

C. Zhou, R. Kumar, S. Jiang
2006 IEEE Transactions on Automatic Control  
Nondeterministic specifications are also meaningful when the system to be controlled has a nondeterministic model due to the lack of information (caused for example by partial observation or unmodeled  ...  Language equivalence is not an adequate notion of behavioral equivalence for nondeterministic systems, and instead we use the finest known notion of equivalence, namely the bisimulation equivalence.  ...  Nondeterministic specifications are also meaningful when the system to be controlled has a nondeterministic model due to the lack of information (caused for example by partial observation or unmodeled  ...

A Small Model Theorem for Bisimilarity Control Under Partial Observation

Changyan Zhou, Ratnesh Kumar
2007 IEEE Transactions on Automation Science and Engineering  
The paper addresses the issue of control of nondeterministic systems subject to nondeterministic specifications, under a partial observation of events.  ...  The paper extends our prior result on decidability of bisimulation equivalence control reported in [7] , [8] from the setting of complete observations to that of partial observations.  ...  INTRODUCTION We study the control of nondeterministic discrete event systems (DESs).

A process-theoretic approach to supervisory control theory

J. C. M. Baeten, D. A. van Beek, B. Luttik, J. Markovski, J. E. Rooda
2011 Proceedings of the 2011 American Control Conference  
The new approach provides for a generalized characterization of controllability of nondeterministic discrete-event systems.  ...  To this end, we investigate partial bisimulation preorder, a behavioral preorder that is coarser than bisimulation equivalence and finer than simulation preorder.  ...  Other works tackle nondeterministic systems as a set of deterministic systems, by requiring controllability of all underlying deterministic systems to induce controllability of the nondeterministic system  ...

Towards Supervisory Control of Interactive Markov Chains: Controllability

J. Markovski
2011 2011 Eleventh International Conference on Application of Concurrency to System Design  
We propose a model-based systems engineering framework for supervisory control of stochastic discrete-event systems with unrestricted nondeterminism.  ...  To this end, we define a new behavioral preorder, termed Markovian partial bisimulation, that captures the notion of controllability while preserving correct stochastic behavior.  ...  Acknowledgment We thank Nikola Trčka for his useful comments and remarks on a preliminary draft of this paper.  ...

SUPERVISORY CONTROL PROBLEMS FOR NONDETERMINISTIC DISCRETE-EVENT SYSTEMS: A LOGICAL APPROACH

Sophie Pinchinat, Jean-Baptiste Raclet
2005 IFAC Proceedings Volumes  
In particular, these transformations are used to reduce control problems for nondeterministic systems to control problems under partial observation for deterministic systems.  ...  We answer a wide range of control problems for nondeterministic discrete-event systems, relying on recent works based on a second order logic approach for deterministic systems.  ...  CONCLUSION We have proposed two transformations that are used to reduce control problems for nondeterministic systems to control problems under partial observation for deterministic systems.  ...
