Abstract
Systems, devices, and methods for active vibration control using circular force generators. In one aspect, a vehicle includes a vehicle frame, a cabin, an engine, and a number of vibration control devices mounted on the vehicle frame. Each vibration device includes a circular force generator comprising at least one mass and at least one motor configured to rotate the mass. The vibration control devices are configured to perform active vibration control to reduce noise and/or vibration within the cabin resulting from the engine deactivating a subset of cylinders in operation.
