摘　　要：本文的目的是分析GMM作动器在高压输电塔结构中的优化布置方法。方法采用MATLAB软件编写了适应度函数程序,并利用遗传算法工具箱进行了相应的优化计算,编写了LQR控制算法程序,输入EL-Centro地震波,进行了无控结构、受控结构在随机布置和优化布置GMM主动控制系统时的地震响应分析。结果表明,GMM主动控制系统对高压输电塔结构的地震响应控制效果明显,一般情况下,受控结构在优化布置时的地震位移响应可比无控结构的地震位移响应减小35%左右,并且比随机布置时的地震位移控制效果要高20%。本文对高压输电塔结构的动力特性和振动控制进行了研究,得到了一些对实际工程抗震设计具有参考意义的结论。The purpose of this paper is to analyze the GMM optimization layout method of active control system in the power transmission tower structure.The research method based on genetic algorithm,fitness function was witted by MATLAB,and the relative optimization calculation was achieved by MATLAB＇s GADS toolbox.LQR active control algorithm was witted and EL-Centro seismic wave was input,and then the dynamic simulation analysis of the uncontyolled and controlled structure under random and genetic algorithm of GMM active control system was done by LQR active control algorithm.The result showed that the GMM active seismic control method and the corresponding active seismic control system can easily control model of seismic response of the power transmission tower structure.The control effect can reach more than 35%generally.The dynamic properties and the vibration control of transmission tower were studied,and some reference significance conclusions for practical engineering seismic design were obtained.
