摘要

本文将模糊控制理论用于建筑结构地震反应的控制。将地震波加速度作为模糊控制器的输入变量，通过模糊推理运算，得到控制力的大小。在模糊控制器中使用了七条模糊控制规则，并考虑实际控制系统时间滞后，通过数值计算说明引入模糊推理运算后，控制系统的输入输出为非线性关系。模糊开环控制能有效地减小建筑结构的地震反应。
In this paper, the application of fuzzy set theory to structure vibration control under earthquake is introduced. A static fuzzy controller based on earthquake acceleration is developed.The controller can simulate nonlinear force control related to one variable via fuzzy relations implemented by linguistic rules. It is demonstrated that earthquake response of structure can be decreased by the method of fuzzy open-loop control. The effect of time delay in actuator on response of structure under earthquake is also studied.
