This study is on the development of energy dissipation control algorithms for vibration control of a 76 -story building under wind excitation. Velocity feedback, bang-bang, and energy gain control algorithms are proposed based on the Lyapunov stability theory and the performance of them are evaluated and compared. Saturation problem is considered in the design of velocity feedback and energy gain control algorithms, and chattering problem in bang-bang control is solved by using boundary layer. Numerical results show that the proposed control algorithms can dissipate the structural energy induced by wind loads, and thus they provide good control performance.
