Abstract：In this paper,the modeling work has been done for the flexible building structure with n-th order of freedom and the reduced model can be gotten to design the controller for ATMD.According to the analysis,the displacement and velocity of the building structure can be chosen as the output feedback variables for the controller.By using the equivalent two-port model of the building structure with ATMD,a robust controller can be designed for ATMD based on the H∞/μ frequency shaping synthesis theory.With the results of simulation,we have found that the control algorithm is very effective.The small mass has the reasonable movement space and the controller has the reasonable output energy.The system has good robustness for performance and stability in case of parameter variations and unstructured uncertainty caused by system un-modeling parts and system model reduction.
