| 中文摘要: |
| 针对目前采用Montecarlo法或按泊松分布来计算振动主动控制系统可靠性计算量较大的缺点，本文提出了修正模型可靠性概念，并定义一个可靠性评价指标，以期通过修正模型的可靠性来问接反映控制系统的可靠性。本文以框架结构为研究对象，在修正方法上选择了计算量小且修正精度较高的拉直算法，为验证提出的可靠性指标的可行性，对四组设计参数分别进行了修正模型和地震作用下的广义预测控制可靠性分析，从结果对比可知，本文所定义的可靠性指标具有一定的可行性，并且本文方法计算量较小。 |

| In view of the defect of considerable calculation effort paid when Montecarlo&Possion distribution are adopted to solve the reliability of vibration control system. In the paper, a conception of the reliability of amended model and relative evaluation index are presented so as to reflect indirectly the reliability of vibration control system. Meanwhile, frame structures are used as study object, the straightened algorithm which has better calculation precision with fewer calculation time is chosen as amended way. Four group design parameters are used to demonstrate the feasibility of the proposed method, by comparing the reliability results of amended models and the generalized predictive control under the action of earthquake. It indicated that the proposed index is feasible and needs less calculation time. |
