Abstract

This paper reports the results of a research activity conceived toward the realisation of stand-alone semiactive control devices.

The goal is to avoid the need for a data acquisition which would require the presence of a computer. On the other side, in most practical situations as in earthquake engineering, one must monitor the system response by accelerometers, while control algorithms are based on the current velocities.

An analog device able to directly perform the integration of the measured time history is conceived and implemented. Its behaviour is compared with the true velocity in a numeric example, and with a software estimation alternative during a laboratory test.
