Abstract
A machine includes an internal combustion engine, and an exhaust particulate filter system coupled therewith having an exhaust particulate filter for trapping particulates in exhaust from the internal combustion engine. A control system for the exhaust particulate filter includes a sensing mechanism such as an RF soot sensor and a data processor coupled with the sensing mechanism and configured to output a moisture compensation signal responsive to a pattern of inputs from the sensing mechanism indicative of moisture within the exhaust particulate filter, for controlling regeneration thereof.
