摘要
针对动力设备振动线谱的综合控制问题,建立了主动吸振系统模型,推导了主动吸振系统动力学方程,同时开展了最优反馈控制技术研究,并进行了反馈控制仿真分析.仿真结果表明,最优反馈控制算法在10~300Hz频带内可实现4根线谱约20dB的抑制效果.
A model of active vibration absorber was established, and the active vibration absorption dy- namics equations were deduced. The optimal active feedback control technic was described, and the effect of the optimized feedback weighted function on the control performance had have been presen- ted. Simulation of the optimal feedback control system showed that when band spectral is between 10Hz to 300Hz, about 20dB suppression in multiple line spectrums can be achieved.
