The active control for forced structural vibration is studied in this paper. The optimum control laws for both the general linear damping systems in the physical space and the linear proportional damping systems in the modal space are introduced. The control law for structural vibration under the multifrequency excitation is also discussed. The results of computer simulation show that a better effect of vibration control could be obtained and the amplitude of vibration could be greatly reduced according to the active control laws presented in this paper.
