Method and apparatus for estimating an actual magnitude of a physical parameter on the basis of three or more redundant signals

摘要

An apparatus includes at least three redundant signals each indicative of a sensed magnitude of a parameter. Parity space and fuzzy logic techniques may be used to provide a signal representing an estimate of the actual magnitude of the parameter. A method for generating an estimate of an actual magnitude of a parameter provides at least three redundant signals may use parity space and fuzzy logic to produce a signal representing an estimate of the actual magnitude of the parameter.
