Methods, devices, and/or systems for controlling vibration and/or acoustic noise. An exemplary method senses noise and/or, for example, rotational speed of a rotating shaft, determines control parameters and actuates one or more actuators. An exemplary device includes a controller configured to receive information, determine control parameters and actuate one or more actuators. An exemplary system includes one or more sensors, a processor and one or more actuators. Various exemplary methods, devices, and/or systems are optionally suitable for use with turbochargers and/or other boost systems.

Noise control

A control system for a variable-geometry turbocharger includes a supervisor logic () selecting a pulse control output () for large variation of desired and previous control signal inputs exceeding a threshold differential and a normal control signal () for small control signal input changes. The control system calculates an amplitude and duration for the pulse control output based on input control signal variation or the actual versus desired position of the variable-geometry system in the turbocharger.

Control system for improved transient response in a variable-geometry turbocharger

Methods, devices, and/or systems for controlling intake to and/or exhaust from an internal combustion engine. An exemplary method for controlling intake charge pressure to an internal combustion engine includes determining one or more control parameters based at least partially on an intake charge target pressure; and outputting the one or more control parameters to control an electric motor operatively coupled to a compressor capable of boosting intake charge pressure and to control a variable geometry actuator capable of adjusting exhaust flow to a turbine.
