摘要
动力吸振器作为抑制特定频率范围内结构物过大振动的有效装置,一直是理论研究和工程应用中的热门课题.本文针对在工作环境比较复杂噪声信号较多的情况下,在频域时域内分别采用遗传算法和LQR的控制方法,对主动动力吸振器进行了优化,数值计算结果表明,说明经过遗传算法优化,再经过LQR的控制系统能较好的适应噪声信号较多的情况.
As the inhibition of a specific frequency range and too large vibration effective device,dynamic vibration absorber has always been a popular topic in theoretical research and engineering applications.Genetic algorithm in the frequency domain and LQR control methods in the time domain were used to optimize the active dynamic vibration absorber working in the complicated condition.The results which were verified by numerical simulations suggested that after genetic algorithm and LQR control system optimization the active dynamic vibration absorber can better adapt to complicated condition.
