Abstract
A method and apparatus for adaptive profile correction for rotating position encoders in reciprocating engines measures a raw engine speed derived from a rotating position encoder (107) driven by a reciprocating engine. A first corrected engine speed (1103) is provided dependent on the raw engine speed and a predetermined first encoder profile while the engine is operating bounded within a first speed range (905), and a second corrected engine speed (1103) is provided dependent on the raw engine speed and a predetermined second encoder profile while the engine is operating bounded within a second speed range (913).
