Abstract
Methods and systems are provided for improving boost response. A continuously variable compressor recirculation valve and a wastegate are adjusted in complementary frequency bands to move compressor operation away from a surge limit and reduce boost delivery errors. An intake throttle is also concurrently adjusted to offset manifold air-flow rate errors resulting from the wastegate or recirculation valve adjustments.
