Abstract
An apparatus, system, and method are disclosed for providing system feedback from combined input values in a sensor-based control system wherein the reliability of a sensor response is questionable under defined conditions. The apparatus, in one embodiment, is configured to determine an output value. The apparatus may include an input module for receiving input from a sensor configured to provide a sensor response, an estimated expected response value, and a control module for determining an output value based on input from the sensor response and from the expected response value. To determine an output value, the sensor response and the expected response value may be weighted according to a predicted reliability of the sensor response or the model. The system may be embodied in an exhaust gas after-treatment system.
