The Semi-active Control Study In consideration of the Fluid-solid Interaction of the Aqueduct Structure

Based on the aqueduct structure model for dynamic analysis of fluid-solid interaction,the branch-and-bound Hrovat optimal control algorithm is put out to the study the semi-active control based on active variable damping for large aqueduct.It is concluded that active variable damping control device can effectively control response of longitudinal virations.The Hrovat optimal control algorithm can track and achieve the target avtive control force effectively.
