Abstract
To study power flow transmission and active control of the frame structure under the influence of disturbance, firstly, the kinetic model of frame structure is established by wave method and the accurate dynamic response is obtained. Then power flow transmission of structure is determined. The power flow is used as the objective function, and the optimized control force magnitude and phase are obtained by optimization algorithm, which is applied to the frame structure. Ultimately, active control of power flow for frame structure is realized. Based on active control method of power flow for frame structure, the numerical analysis and experimental validation are made. The results show that the dynamic responses of frame structure based on the wave method are accurate and reliable. The present active control method of power flow can efficiently reduce the jitter of the frame structure in the whole frequency domain, showing that the present active control of power flow based on the wave method is valid.
