Abstract
A method for operating a turbocharged engine includes adjusting turbocharger rotational acceleration or deceleration in response to one or more resonant frequencies. Additionally in some examples, the method may further include increasing turbocharger rotation in response to one or more resonant frequencies during a first condition, and increasing turbocharger deceleration in response to one or more resonant frequencies during a second condition, the second condition different from the first condition. In this way, it is possible to enhance the useful life cycle of the turbocharger and associated engine by limiting the operating time in a resonant frequency band.
