title: An Integrated Monitor-Diagnosis-Reconfiguration Scheme for (Semi-) Autonomous Systems creator: Luo, Yi creator: Wagner, Achim creator: Zouaghi, Leila creator: Badreddin, Essameddin subject: 004 subject: 004 Data processing Computer science description: A nested monitoring, diagnosis and reconfiguration (MDR) scheme is proposed for a Recursive Nested Behavior based Control structure (RNBC)constituting a generic system architecture for (semi-) autonomous mobile systems. Each behavior layer within the RNBC structure is associated with a MDR schema, which is responsible to ensure the dependability of every single layer. An online dependability measurement and diagnosis procedure is integrated into monitor and diagnosis blocks under consideration of performance and safety acceptability factors. The reconfiguration blocks within the MDR-scheme switch from components with unacceptable behavior to redundant components, which may have degraded performance but more robust and safe behavior. The MDR blocks at each layer are nested through unified interfaces in order to utilize the distributed modeling of system behavior and to facilitate the system design and implementation process. In a small case study the MDR scheme is demonstrated for an assistant wheelchair on the body velocity control and axis velocity control levels. Simulation results show the feasibility and effectiveness of the approach. date: 2009 type: Conference Item type: info:eu-repo/semantics/conferenceObject type: NonPeerReviewed format: application/pdf identifier: https://archiv.ub.uni-heidelberg.de/volltextserverhttps://archiv.ub.uni-heidelberg.de/volltextserver/10078/1/An_Integrated_Monitor_Diagnosis_Reconfiguration_Scheme_for_Semi_Autonomous_Systems.pdf identifier: DOI:10.11588/heidok.00010078 identifier: urn:nbn:de:bsz:16-opus-100781 identifier: Luo, Yi ; Wagner, Achim ; Zouaghi, Leila ; Badreddin, Essameddin (2009) An Integrated Monitor-Diagnosis-Reconfiguration Scheme for (Semi-) Autonomous Systems.
