| 中文摘要: |
| 提出了将H∞控制及平衡降阶法应用于结构主动控制的新方法。该方法首先利用平衡降阶法对结构进行降阶,然后利用降阶模型构造出H∞控制器和H∞观测器对结构进行控制;同时结合复模态理论和虚拟激励法,给出了系统分析的有效途径。本文最后以海洋平台地震响应的ATMD主动控制为例,验证了本文方法的有效性。 |
| 英文摘要: |
| 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. |
