Abstract
A multivariable controller that models the interaction between groups of sensors and groups of actuators during the operation of an engine. By accounting for the interactive effects that a group of actuators has on a sensor or group of sensors, improved system performance may be achieved. When emission sensors are used, such as NOX and/or PM sensors, the multivariable controller may help control the various engine actuators to reduce emissions of the engine.
