Active control of helicopter vibration

Computing & Control Engineering Journal, 1994
The reduction of helicopter vibration is of great importance to the helicopter industry and considerable effort has been devoted to research into active methods for vibration reduction. The article describes how active control techniques can offer good vibration reduction over significant areas of the fuselage and also provide the capability to adapt ...

Active control of structural vibration

The Journal of the Acoustical Society of America, 1986
In general, structures represent distributed-parameter systems described by partial differential equations. Strictly speaking, vibration control in distributed structures requires distributed sensors and actuators. Practical considerations demand that control be carried out by means of discrete components.

Algorithms in Active Vibration Control

2012
With the advent of active vibration control (AVC) systems and their gradual transfer to commercial products, building a solid knowledge base on feedback systems and their components has become increasingly important for the vibration engineering community.

Active control of flexural vibrations

Journal of Sound and Vibration, 1987
The active control of disturbances propagating along a waveguide is considered with particular reference to the control of flexural vibrations in thin beams. The control system consists of a number of point sensors and point exciters distributed in some manner along the waveguide.

Active Control of Structural Vibration

2006
In its most general form, active control can be used to arbitrarily modify the vibration response of a structure, although in engineering applications the objective is normally to attenuate the vibration. Many actuators and sensors are required to control the vibrations of a large structure, and conventionally these are connected using a single ...

Actuator for active vibration control

The Journal of the Acoustical Society of America, 1994
An electromagnetic actuator is disclosed which is especially suitable for active vibration control applications. The actuator may be either of the moving coil (C2) or moving magnet (M1, M3) type so that a moving element (M1, M3, C2) undergoes reciprocal motion in response to an electrical input signal.
