Abstract
A modified optimal linear control algorithm is proposed to demonstrate the effectiveness of the active control system in reducing inelastic structural dynamic responses using elastic displacement feedback. Effectiveness of the proposed algorithm is then demonstrated by studying the control energy of the controlled structure. Numerical simulation using various single degree of freedom systems is performed and results show that there always exists a point where the control energy dissipation is maximal, and this optimal point is dependent on the structural characteristics as well as the earthquake excitation.
