Soft Computing Algorithm to Data Validation in Aerospace Systems Using Parity Space Approach

This paper deals with the problem of data validation of an instrumentation system applied in the aerospace area. The fault diagnosis method used for validation is based on the principle of the parity space approach. Residuals are generated from the analytical redundancy relations given by the model and the important number of sensors. A procedure allows for systematic computation of all the redundancy equations for the residual generation phase. The additional concept--residuals structuration--is necessary to isolate detected faults. The data validation task consists of isolating failing data and sending only valid information to a control system. An application to an aerospace system illustrates the proposed algorithm.
