摘要： In one embodiment, an engine system (10) may include an engine control system (12) configured to receive a first pressure signal transmitted from a first pressure sensor (43) disposed downstream from a throttle valve (14), receive a first temperature signal transmitted from a first temperature sensor (43) disposed downstream from the throttle valve (14), derive a first pressure representative of the first pressure signal, derive a first temperature representative of the first temperature signal, derive a desired air-fuel mixture flow through the throttle valve (14), derive a first throttle position using a model (60), wherein the model (60) is configured to use the desired air-fuel mixture flow, the first pressure, and the first temperature as model input, derive a second throttle position using a map (61), compare the first and second throttle positions, and apply the first throttle position to control the throttle valve (14) when the first and second throttle positions are within one or more calibrated thresholds.
