Abstract
An integrated closed loop engine control is disclosed in which the fuel delivery and timing functions of the engine are closed about a measurement of the engine's instantaneous rotational velocity. Signals indicative of the profile of each torque impulse imparted to rotary output member of the engine from the burning of an air/fuel mix in the engine's combustion chambers are generated and electrically analyzed to detect perturbation caused by deviations of at least two different engine operational parameters from desired values. Feedback correction signals indicative of the magnitude of the detected perturbations are generated to correct the fuel delivery and timing functions of an engine control to minimize the difference between the actual operating parameters and the desired values. In an ultimate embodiment, the correction signals are applied to the engine control through a state variable matrix integrating the control of at least one engine parameter as a function of at least two different correction signals.
