摘要
A coordinated air-fuel controller (13) and associated method provide a fuel controller (23), a combustion air controller (25) and a steady-state air versus fuel model (15). The fuel controller (23) generates a fuel control output signal (33) and the combustion air controller (25) generates a combustion air control output signal (47). The fuel controller (23) determines a preliminary fuel control signal (41) based on at least one of first and second loop control signals, and determines the fuel control output signal (33) based on the preliminary fuel control signal (41). The steady-state air versus fuel model (15) processes the preliminary fuel control signal (41) to determine an expected steady-state combustion air control signal (53). The combustion air controller (25) determines a preliminary combustion air control signal (51) based on at least one of a third loop control signal (37c) and a fourth loop control signal (37c), and determines the combustion air control output signal (47) based on the preliminary combustion air control signal (51) and the expected steady-state combustion air control signal (53).
