Abstract
The measurement system having multiple sensors for sensing the same physical magnitude comprises at least one set of n redundant sensors or of models representing the same physical magnitude in order to deliver n measurement signals, a fusion unit for performing fusion that is the result of multiplexing the n measurement signals in order to deliver a single multiplexed output signal resulting from the fusion of the n measurement signals, and a reconditioned UKF receiving the multiplexed output signal to output a signal constituting the best estimate of the measurement of the physical magnitude after rejecting signals representative of a sensor failure.
