【Abstract】 In this paper, an application of Intelligent Control Algorithm to semi-active control of MR dampers is proposed for engineering structures. The control signal is optimized directly by the micro genetic algorithm to obtain the numerical relation between the control signal and the system output. And then, this relation is stored in the weight value of a trained artificial neural network, which can be used for another structure subjected to other seismic inputs. The results of an example indicate that the MR damper using semi-active control algorithm can efficiently reduce the structural responses induced by earthquakes.更多还原
