A simplified fault logic accomodation control which utilizes fuzzy logic to assist in calculating a preselected weighted average of the values of two redundant sensors that are sensing the same parameter. A synthesized, third, predicted value of the parameter is used in the fuzzy logic to arbitrate

A synthesized, third, predicted value of the parameter is used in the fuzzy logic to arbitrate between the two sensed values.

[ Having described the invention with sufficient clarity that those skilled in the art may make and use it, what is claimed is:] [1.] In a control system having redundant sensors providing at least two sensed values of a single parameter being measured, and having means for generating a synthesized value of said parameter; a method of determining a single output value of said parameter for use in the control system, comprising the steps of:determining a first error by comparing said sensed values to one another;determining a second error by comparing said sensed values to said synthesized value;determining a graded membership of said first and second errors from a fuzzy logic look-up table; andcalculating a preselected weighted average of said sensed values based on said graded membership, said preselected weighted average being the single output value of said parameter for use in the control system.
