CLOSED-LOOP ENGINE CONTROL WITH FEEDBACK TORQUE ERROR COMPENSATION

摘要

A closed-loop engine control system (l0) is disclosed in which an engine (l2) is controlled to provide power to a load (l4,l8) as a function of measured feedback torque. A programmable digital controller (24) modifies the feedback torque by adding to it a synthesized correction torque provided by the product of the engine polar moment of inertia and the engine acceleration. The modified feedback torque is used for either closed-loop torque or horsepower engine control.
