Vibration Control

Micromega Dynamics has developed innovative solutions for active vibration control of flexible systems. These technologies are applicable to either micro-vibration (space interferometry, optical devices, ...) and large structures (bridges, railways, ...). Vibration control is essential for high-precision machining, high accuracy visual inspection, comfort, acoustics,...

The proposed control technology relies on simple, local controllers that are very robust to system uncertainty.

Active vibration control makes it possible to achieve unequal performances in areas where passive methods have show their limits.

Depending of the application, a wide range of actuators (i.e. piezoelectric actuator, piezo patch, proof-mass actuator, MR fluid) and sensors (i.e. force, displacement, strain, acceleration sensors) have been successfully implemented. Because of the sensitivity of structural control to modal uncertainties, the emphasis of the control is put on the robustness. Most of the time simple local and decentralized controllers can be selected.
