摘要
A controller including a self-tuning circuit for controlling a pressure system to output an input pressure corresponding to an input pressure value using an adaptive fuzzy control system and updating dosing command values of a dosing command table for controlling a dosing unit of an aftertreatment system. The self-tuning circuit is configured to determine an input pressure value and generate a pressure control signal using the adaptive fuzzy control system based on the input pressure value, a detected input pressure, and an error amount. The self-tuning circuit is further configured to regulate the input pressure of reductant to the dosing unit from a reductant tank using a pressure control signal for a pressure control device. The self-tuning circuit is further configured to update a dosing command value of a dosing command table of the controller in conjunction with regulating the input pressure of reductant.
