Abstract
Disclosed is a method and apparatus for controlling operation of an engine whereby there is a known general function relating an engine control input to the engine output. This known control function has a number of structures or method steps which accomplish the following functions. The value of at least one engine output is measured; a base value of at least one engine input is supplied. A value of the engine output is determined based upon a predetermined function of the base value of the supplied engine control input; the measured value of the engine output is compared with the determined value of the engine output; in response to the comparison, base values of the two parameters in the predetermined function are adjusted; and the base value of the engine control input is adjusted based upon the adjustment to the two parameters.
