“…The method is based on the overlap of Gaussian confidence regions of two local sensor estimates in a decentralized system. A sensor voter algorithm to manage three redundant sensors was presented in Reference [ 141 ]. Inconsistency detection for hypersonic cruise vehicles (HCVs) based on redundant multisensor navigation systems was proposed in Reference [ 142 ].…”

The paradigm of multisensor data fusion has been evolved from a centralized architecture to a decentralized or distributed architecture along with the advancement in sensor and communication technologies. These days, distributed state estimation and data fusion has been widely explored in diverse fields of engineering and control due to its superior performance over the centralized one in terms of flexibility, robustness to failure and cost effectiveness in infrastructure and communication. However, distributed multisensor data fusion is not without technical challenges to overcome: namely, dealing with cross-correlation and inconsistency among state estimates and sensor data. In this paper, we review the key theories and methodologies of distributed multisensor data fusion available to date with a specific focus on handling unknown correlation and data inconsistency. We aim at providing readers with a unifying view out of individual theories and methodologies by presenting a formal analysis of their implications. Finally, several directions of future research are highlighted.

“…Brown et al in [18], where real values were abstracted by integer values and integrators were not used. The work [20] analyzed the Simulink model with real numbers by both simulation and formal verification, and then estimated the impact of rounding errors caused by the floating-point implementation using SMT solvers and abstract interpretation.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract This work presents a formal verification process based on the Systerel Smart Solver (S3) toolset for the development of safety-critical embedded software. In order to guarantee the correctness of the implementation of a set of textual requirements, the process integrates different verification techniques (inductive proof, bounded model checking, test case generation and equivalence proof) to handle different types of properties at their best capacities. It is aimed at the verification of properties at system, design, and code levels. To handle the floating-point arithmetic (FPA) in both the design and the code, an FPA library is designed and implemented in S3. This work is illustrated on an Automatic Rover Protection (ARP) system implemented on-board a robot. Focus is placed on the verification of safety and functional properties and on the equivalence proof between the design model and the generated code.
