China In this work,the use of a newly proposed HMD is studied to protect Guangzhou New TV Tower against undesirable vibration levels and improve its serviceability,which is composed of a TMD with twostage damping levels,and a small AMD driven by linear induction motors and mounted on the TMD. For convenient analysis,the tower is simplified as 51 connected rigid panel series model. A reduced-order model of the simplified system is developed using an improved eigenmode reduction method. The fluctuating wind velocity time series applied on the Tower is simulated by employing ARMA method. An H2/LQG control algorithm and a fuzzy logic control algorithm are employed for active controller design. The performance of the proposed HMD system is investigated and compared with the corresponding TMD and ATMD systems. Numerical simulation and experimental verification studies are also conducted to test the performance of the proposed control system. Results show that the proposed HMD system can achieve outstanding performance for different input excitation and FLC controller has better control efficiency than LQG controller.
