| Abstract: |
| A new method of active structural control which combines H∞ controllers with balanced reduction method is presented in this paper. The model reduction is first carried out by balanced reduction method, then H∞ controllers and H∞ observers are used for structural control. An effective analysis approach is given in terms of complex modal superposition method and pseudo-excitation method. The method is validated by an example of ATMD active control of seismic responses of offshore platform. |
