An essential requirement for its application is sufficient spatial redundancy given by a structurally necessary condition of variance estimability. These reconciliation methods are based on the usual least squares and Kalman filtering techniques. Numbers correspond to the affiliation list which can be exposed by using the show more link.

Zasadzinski3rd Mohamed Darouach38.33 · University of LorraineAbstractMethods of data reconciliation are necessary for correct process control. The plenary papers present the state-of-the-art and an overview in the areas of aircraft and nuclear power stations, because these safety-critical system domains possess the most highly developed fault management and A few studies have addressed this problem (Almasy and Mah, 1984; Keller et al., 1992). Even if the covariance is already known, it still needs to be validated.

Also, the issue of the probability distribution of data cannot be addressed satisfactorily when averaging is performed and steady state is assumed (Bagajewicz, 1996 ).

The differential equations representing this system are first rearranged to obtain a system of equations containing only redundant measurements.

It has been claimed in several papers (Almasy & Mah, 1984; Keller, Zasadzinski & Darouach, 1992; Chen, Bandoni & Romagnoli, 1997) that the variance used in steady state data reconciliation is A.

These equations are formally integrated using polynomial approximations, and the reconciliation is then performed using analytical solutions. Strategies for coupling data reconciliation with real-time optimization and automatic control techniques are also proposed. Click the View full text link to bypass dynamically loaded article content.

He has worked extensively with industry in recent years especially in the automotive sector. Consequently, the definition or calculation of this statistical property of the data is of prime importance in implementing a reliable and accurate reconciliation procedure. An essential requirement for its application is sufficient spatial redundancy given by a structurally necessary condition of variance estimability.
