Abstract
Systems, methods, and computer program products for directional force weighting of an active vibration control system involve arranging a plurality of force generators in an array, identifying individual component forces corresponding to force outputs of each of the plurality of force generators, determining a combination of the individual component forces that will produce a desired total force vector, and adjusting the outputs of each of the plurality of force generators such that the combination of the individual component forces are at least substantially similar to the desired force vector.
Claims15
An active vibration control system comprising:
- a plurality of force generators arranged in an array, wherein the plurality of force generators are placed in close proximity to one another for multi-directional force generation, each of the plurality of force generators being configured to generate an individual component force, the individual component force corresponding to a force output;
- and
- a controller configured to individually control each of the plurality of force generators by applying a force mapping matrix that converts the individual component force to a desired component forces having degrees of freedom corresponding to the desired force vector in order to achieve a combination of the individual component forces that produces a desired total force vector.
The plurality of force generators are arranged in pairs.
A method for directional force weighting of an active vibration control system, comprising:
- arranging a plurality of force generators in an array;
- for each of the plurality of force generators, identifying individual component forces corresponding to force outputs of each of the plurality of force generators;
