Reconfigurability analysis for reliable fault-tolerant control design
International Journal of Applied Mathematics and Computer Science, 2011Co-Authors: Abdelmadjid Khelassi, Didier Theilliol, Philippe WeberAbstract:In this paper the integration of reliability evaluation in Reconfigurability analysis of a fault-tolerant control system is considered. The aim of this work is to contribute to reliable fault-tolerant control design. The admissibility of control Reconfigurability is analyzed with respect to reliability requirements. This analysis shows the relationship between reliability and control Reconfigurability defined generally through Gramian controllability. An admissible solution for Reconfigurability is proposed according to reliability evaluation based on energy consumption under degraded functional conditions. The proposed study is illustrated with a flight control application.

Evaluation of fault tolerant system against actuators aging applied to flotation circuit
IFAC Proceedings Volumes (IFAC-PapersOnline), 2011Co-Authors: Abdelmadjid Khelassi, Philippe Weber, Didier Theilliol, Christophe AubrunAbstract:The main contribution of this paper concerns the Reconfigurability evaluation of fault tolerant control system with respect of the reliability requirements and actuators aging. Based on the relationship between the energy consumption defined through the Gramian controllability and the actuators aging under degraded functional conditions, a new Reconfigurability index for a reliable design is proposed. A flotation circuit is considered to highlight the performance of the proposed method. Flotation circuit require dependability conditions which can be guaranteed with the proposed reliable fault tolerance approach. © 2011 IFAC.

Reconfigurability analysis for reliable fault-tolerant control design
2009Co-Authors: Abdelmadjid Khelassi, Didier Theilliol, Philippe WeberAbstract:This paper interests to the Reconfigurability of fault-tolerant control system based on the reliability analysis of components. The aim of this work is to present the need of reliability analysis in fault-tolerant control design. The admissibility of system Reconfigurability with respect to the reliability constraints is considered in this research. This analysis proves that the control Reconfigurability is a system property that not only related to the Gramian controllability but also to the overall system reliability. An admissible solution for Reconfigurability indicator generation is proposed according to the reliability evaluation in degraded mode. A linearized aircraft model is considered as an example to illustrate this approach.

On Reconfigurability for actuator faults under reliability constraints
2009Co-Authors: Abdelmadjid Khelassi, Didier Theilliol, Philippe WeberAbstract:This paper interests to the properties of fault-tolerant control system with respect to reliability of components. The aim of this paper is to present the need of reliability analysis in fault-tolerant control design. The focus of our study is on the Reconfigurability analysis of systems with actuator faults under reliability constraints. This analysis proves that control Reconfigurability is a system property that is not only related to Gramian controllability and controllability of the system but it's related also and directly to overall system reliability. In this context, Reconfigurability index is proposed. A flotation circuit is taking like an example to illustrate this work. In fact, flotation circuit is one of the most interactive mineral's processing operation. The interactive nature of flotation circuit results in oscillation of levels and hence of grades and recoveries.

Reconfigurable Communication Networks in a Parametric SIMD Parallel System on Chip
2010Co-Authors: Mouna Baklouti, Philippe Marquet, Jean-luc Dekeyser, Mohamed AbidAbstract:The SIMD parallel systems play a crucial role in the field of intensive signal processing. For most the parallel systems, communica- tion networks are considered as one of the challenges facing researchers. This work describes the FPGA implementation of two reconfigurable and flexible communication networks integrated into mppSoC. An mppSoC system is an SIMD massively parallel processing System on Chip de- signed for data-parallel applications. Its most distinguished features are its parameterization and the Reconfigurability of its interconnection net- works. This Reconfigurability allows to establish one configuration with a network topology well mapped to the algorithm communication graph so that higher efficiency can be achieved. Experimental results for mpp- SoC with different communication configurations demonstrate the per- formance of the used reconfigurable networks and the effectiveness of algorithm mapping through reconfiguration.

IJCAI - Reconfigurability in reactive multiagent systems
2016Co-Authors: Xiaowei Huang, Qingliang Chen, Jie Meng, Kaile SuAbstract:Reactive agents are suitable for representing physical resources in manufacturing control systems. An important challenge of agent-based manufacturing control systems is to develop formal and structured approaches to support their specification and verification. This paper proposes a logic-based approach, by generalising that of model checking multiagent systems, for the Reconfigurability of reactive multiagent systems. Two Reconfigurability scenarios are studied, for the resulting system being a monolithic system or an individual module, and their computational complexity results are given.
