DEFINITION

Classification: 123/339.2

Dynamic state variable model:

(under subclass 339.19) Subject matter wherein the electrically powered adjusting means (a) has a preprogrammed memory of stored values from a previous test phase (e.g., bench test), (b) compares actual engine condition values to the stored values, and (c) anticipates adjustments necessary to control the minimum output shaft operating speed.

SEE OR SEARCH THIS CLASS, SUBCLASS:

350+, for electrical sensing or regulating of engine speed with the engine being part of a closed loop condition responsive feedback system.

395+, for an open loop condition responsive speed regulator for an engine.

418+, for a spark ignition timing control responsive to engine output shaft operating speed.

480, for an electrically actuated fuel injector actuator circuit having a microprocessor.

SEE OR SEARCH CLASS 701, Data Processing, Navigation, and Relative Location,

101+, for control means for an internal-combustion engine including specific computer or data processing details.
