A closed-loop engine control system is disclosed in which an engine is controlled to provide power to a load as a function of measured feedback torque. A programmable digital controller 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.

In a closed-loop system in which an engine is controlled to provide power to a load as a function of measured feedback torque, the improvement comprising: means for modifying 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 thereby to compensate the system for the phase and amplitude error between the measured feedback torque and the actual gross engine torque caused by the circumstance that the measured feedback torque represents the actual gross engine torque less the torque required to accelerate the engine moment of inertia, whereby the modified feedback torque more nearly represents the actual gross engine torque thereby improving the response and stability of the system.
