Definition of mechanical design parameters to optimize efficiency of integral force feedback
TL;DR: In this paper, the authors proposed a non-centralized IFF control strategy to increase the implementation efficiency of a plate-based control system, not only in terms of induced damping and signal magnitudes, but also in the sense that the best designed system can be coupled with a noncentralized approach.
