Various methods and systems are provided for detecting surge of a turbocharger during engine operation. As one example, a system includes an engine coupled to a low pressure turbocharger and a high pressure turbocharger; and a controller with non-transitory instructions stored in memory that when executed during operation of the engine cause the controller to: indicate an occurrence of surge of the high pressure turbocharger in response to a deviation of a modeled speed of the high pressure turbocharger from a measured speed of the high pressure turbocharger by a threshold amount, where the modeled speed tracks the measured speed during non-surge conditions, as engine operating conditions change.
