Self-tuning Integral Force Feedback
نویسندگان
چکیده
A self-tuning procedure is proposed for an active structural element with collocated sensing and actuation (a so-called ‘Smart Disc’). The procedure aims at optimal active damping by means of Integral Force Feedback control. In case the behavior of the structure to be damped may be described by a single dominant vibration mode, self-tuning is realized in two fairly simple steps: (1) recursive estimation of three system parameters and (2) determination of the optimal controller parameters. However, if the assumption concerning a single dominant vibration mode does not hold, both steps in the selftuning procedure may easily fail.

Seismometers and MEMS accelerometers use the force-balance principle to obtain measurements. In these instruments the displacement of a mass object by an unknown force is sensed using a very highresolution displacement sensor. The position of the object is then stabilised by applying an equal and opposite force to it. The magnitude of the stabilising force is easily measured, and is assumed to ...
