This paper formulates phase formulation of TMD system, in which the parameters for influence of phase and performance are investigated. Results indicate that both frequency band of vibration reduce and distribution of phase difference change with the parameters of TMD system. The comprehensive optimum control effect for TMD is obtained as the optimum damping and frequency ratio adopted. The increasing mass ratio of TMD can improve both the control performance and control robustness. In addition, theory of phase energy combined with the principle of energy dissipation is employed to obtain the equivalent damping ratio of TMD system. The results show that the proposed equivalent damping ratio is more reasonable than that deduced by white noise.
