- Abstract
- The authors present an evaluation of the potential improvements in seismic disturbance rejection obtained by using active variable damping control in a structure. Using the response to seismic excitation of an optimally controlled variable structue and of a minimax optimally designed fixed structure, the authors obtain an upper bound on the achievable performance and a lower bound on the acceptability of a control system for a variable damping structure.
