This study is based on a benchmark control problem for seismic response of cable-stayed bridges that is introduced to compare the effectiveness of various control algorithms [1,2]. The finite element model of the bridge is arranged according to its modal importance and is reduced to 1/6'th of its size. Special attention is given to the control of critical locations of the bridge response. Among these, the tower shear forces at the deck level were the hardest to reduce by using hydraulic actuators. An uncertainty tolerant design is introduced to account for the design model difference from the evaluation model. Finally, a μ-synthesis based controller is designed and used in the closed loop system simulation of the bridge.
