Hybrid Systems are systems containing both discrete event and continuous variable components. Many recent contributions address crisp situations, where ambiguity or subjectivity in the measured data is absent. In this paper, we propose Fuzzy Hybrid Systems to account for inaccurate measurements and uncertain dynamics. We present a strategy to determine the most appropriate control actions in a sampled data setting. The proposed approach is based on three basic steps that are performed in each sampling period. First, the current discrete fuzzy state of the system is determined by a sensor evaluation. Next, the future discrete fuzzy state is predicted for the possible control actions and the best action, in respect to desired continuous states, is selected. Finally, the decision is cross-evaluated by a limited horizon prediction of the continuous system variables. The proposed method is explained and demonstrated for a variation of the a well-known two-tank scenario.

Fuzzy Discrete Event Systems for Multiobjective Control: Framework and Application to Mobile Robot Navigation Schmidt, Klaus Verner (2012-10-01) Fuzzy discrete event systems (FDESs) have been introduced in recent years to model systems whose discrete states or discrete state transitions can be uncertain and are, hence, determined by a possibility degree. This paper develops an FDES framework for the control of sampled data systems that have to fulfill multiple objectives. The choice of a fuzzy system representation is justified by the assumption of a controller realization that depends on various potentially imprecise sensor measurements. The propos...
Multi-objective decision making using fuzzy discrete event systems: A mobile robot example Boutalis, Yiannis; Schmidt, Klaus Verner (2010-09-29) In this paper, we propose an approach for the multi-objective control of sampled data systems that can be modeled as fuzzy discrete event systems (FDES). In our work, the choice of a fuzzy system representation is justified by the assumption of a controller realization that depends on various potentially imprecise sensor measurements. Our approach consists of three basic steps that are performed in each sampling instant. First, the current fuzzy state of the system is determined by a sensor evaluation. Seco...
Controller synthesis for an I/O-based hierarchical system architecture Perk, Sebastian; Moor, Thomas; Schmidt, Klaus Verner (2008-10-08) In our previous work, a framework for the hierarchical design of discrete event systems has been introduced that is based on a notion of inputs and outputs. I/O-plant models describe the interaction of each subsystem with the operator (or controller) and the environment. By alternation of subsystem composition and controller synthesis, a hierarchy of controllers is obtained that complements a hierarchy of environment models. An admissibility condition was presented that implies liveness while allowing for a...
Abstraction-based supervisory control for recon-gurable manufacturing systems ? Khalid, Harith M.; Kirik, Mustafa Sancay; Schmidt, Klaus Verner (2013-10-21) Reconfiguration control for discrete event systems (DES) is concerned with the realization of different system configurations by modification of the supervisory control loop. In this paper, we study the reconfiguration supervisor design for reconfigurable manufacturing systems (RMS) that comprise multiple components. We construct a modular supervisor for each configuration and system component in order to realize each active configuration and to quickly change between configurations. Different from the exis...
Efficient Abstractions for the Supervisory Control of Modular Discrete Event Systems Schmidt, Klaus Verner (2012-12-01) The topic of this technical note is the nonblocking and maximally permissive abstraction-based supervisory control for modular discrete event systems (DES). It is shown, that an efficient abstraction technique, that was developed for the nonconflict verification of modular DES, is also suitable for the nonblocking supervisory control. Moreover, it is proved that this abstraction technique can be extended by the condition of local control consistency, in order to achieve maximally permissive supervision. Dif...
