COMMANDED AND ESTIMATED ENGINE TORQUE ADJUSTMENT
First Claim
1. An engine control system comprising:
- a first integral module that determines an engine speed (RPM) integral value based on a difference between a desired RPM and a measured RPM;
a second integral module that determines a torque integral value based on a difference between a desired torque output for an engine and an estimated torque of said engine;
a summer module that determines an RPM-torque integral value based on a difference between said RPM and torque integral values; and
a torque adjustment module that determines a torque adjustment value based on said RPM-torque integral value and that adjusts said desired torque output and said estimated torque based on said torque adjustment value.

Abstract
An engine control system comprises first and second integral modules, a summer module, and a torque adjustment module. The first integral module determines an engine speed (RPM) integral value based on a difference between a desired RPM and a measured RPM. The second integral module determines a torque integral value based on a difference between a desired torque output for an engine and an estimated torque of the engine. The summer module determines an RPM-torque integral value based on a difference between the RPM and torque integral values. The torque adjustment module determines a torque adjustment value based on the RPM-torque integral value and adjusts the desired torque output and the estimated torque based on the torque adjustment value.
