ABSTRACT A virtual sensor for normal acceleration has been developed and
implemented in the flight control system of a small commercial aircraft.
The inputs of the virtual sensor are the consolidated outputs of
dissimilar sensor signals. The virtual sensor is a fuzzy model of the
Takagi-Sugeno type and it has been identified from simulated data, using
a detailed, realistic Matlab/SimulinkTM model used by the
aircraft manufacturer. This virtual sensor can be applied to identify a
failed sensor in the case that only two real sensors are available and
even to detect a failure of the last available sensor

    ABSTRACT: Distributed event detection is a popular application in Underwater Wireless Sensor Networks (UWSNs). The Base Station (BS) collect the measurements from multiple sensor nodes, and make a decision based on the sensors’ reports. However, due to the unpredictable moving of underwater sensor nodes and interference among multiple events, it is difficult to guarantee the accuracy of event detection. In this paper, we propose a sensor virtualization approach to deal with the event detection problem in UWSNs. The final decision making at the BS will be implemented with the reports of multiple virtual sensors. Although the events may happen in a large scale, the locations where the events happen are relatively sparse in the underwater environment. Consider the sparse property of events, we employ the technique of compressive sensing to recover the original signal from the correlated sensors’ measurements. Through a proper signal reconstruction, the accurate event detection can be reached with a remarkable low sensing overhead. We implement the sensor virtualization based on the compressive sensing technique. Our approach is suitable for the high dynamic topology of UWSN, and it can improve the accuracy of event detection and reduce energy consumption in UWSNs.

    ABSTRACT: Introduction of Fly-By-Wire and increasing levels of automation improve the safety of civil aircraft significantly, and result in advanced capabilities for detecting, protecting and optimizing A/C guidance and control. However, this higher complexity requires the availability of some key flight parameters to be extended, to keep for a nominal behaviour of the flight control systems. Hence, the monitoring and the consolidation of those signals is a significant issue, usually achieved via many functionally redundant sensors to enlarge the way those parameters are measured. This solution penalizes the overall system performance in terms of weight, power consumption, space requirements, and extra maintenance needs. Other alternatives rely on signal processing or model-based techniques that make a global use of all or part of the sensor data available, supplemented by a model-based simulation of the flight mechanics (analytical redundancy). That processing achieves a real-time estimation of the critical parameters and yields dissimilar signals. Filtered and consolidated information are delivered in unfaulty conditions by estimating an extended state vector including wind components, and can replace failed signals in degraded conditions (virtual probes). Accordingly, this paper describes a new model-based approach allowing the longitudinal flight parameters of a civil A/C to be estimated on-line, through an Aerodynamic Model Inversion. To facilitate onboard implementation, the main aerodynamic coefficients are approximated by a set of surrogate models. Results are displayed to evaluate the performances of that approach in different flight conditions, including external disturbances and modeling errors. They correspond to different simulations and real flight tests.
