Closed-loop engine control with feedback torque error compensation
This patent describes 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. 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, the measured feedback torque represents the actual gross engine torque less the torque required to accelerate the engine moment of inertia. The modified feedback torque more nearly represents the actual gross engine torque thereby improving the response and stability of the system.
