摘要

A control system for an internal combustion engine comprises a primary controller (301), which compares a feedback value to a setpoint value and produces a primary output. The feedback value is an indicator of a measured dynamic quantity in a process (101) in said internal combustion engine. A secondary controller (302) receives an input value and produces a secondary output according to a transfer function. The input value is an indicator of a measurable disturbance affecting the process (101). A combiner (303) receives said primary and secondary outputs and delivers their combination as a control signal to an actuator (104). The secondary controller (302) receives said primary output or a derivative thereof, and adapts said transfer function based at least partly on an aim of maintaining said primary output at a fixed value.
