8.Active Control Principles - ONERA / DADS
 When applied to a structure, instead of creating an antinoise wave, the principle consists of locating vibration sensors on the structure or in the outside space and actuators capable of creating vibrations in the structure to achieve the minimization objective.... The sensors and actuators are coupled with an electronic control system, either an analog system or a digital computer, which calculates the signal to be applied to the actuators in real time....

 The demonstrator equipped with the actuators... 6 actuators were manufactured and installed :... For excitation in the Z direction, only the vertical actuators are used.... In this configuration, the acceleration levels in the Z direction reach several g. The implementation of the active control with all 6 actuators operating reduces the peak levels, as the broadband contributions....
 
10.Microsoft Word - OneraPaper2006 29-01-06 doc
 Pulsed Plasma Actuators for Separation Flow Control... An experimental investigation of separation control using steady and pulsed plasma actuators was carried out on an Eppler E338 airfoil at typical micro air vehicle Reynolds numbers (20, 000Re140, 000). Pulsing was achieved by modulating the high frequency plasma excitation voltage....
