    Abstract: An improved feeder control system is disclosed. The system implements an incremental metering process that incorporates the standard deviation of the material feeder. By intentionally initially under metering at a level corresponding the standard deviation of the feeder, and then subsequently metering a more accurate delivery of materials is achieved. Additionally, the system implements a system for correcting for metering errors caused by gate cycles delays. By incorporating offsets into a feed time when gate cycle time is larger than the feed time, error caused by significant gate cycle times is cured.
