✦ Synopsis
The purpose of this research is to examine a particular non-application-specific active control strategy for reproducing noise and vibration. The mechanical power absorbed by a controller is taken as a cost function to be maximized. The models suggest that an adaptive scheme to maximize the power absorption is good provided that the adaptation is accomplished within the time taken for a wave emitted by the controller to come back to the control point; that interval is called the ''sing around time''. The validity of the strategy has been studied and explored through numerical simulations, the results of which are given in this paper and which describe the scope of the experimental studies to be reported later.
