摘要

为了实现对一种基于磁流变弹性体的主动式自调谐吸振器的减振控制，提出了变步长寻优与反馈控制相结合的控制算法，设计了以TMS320F2812DSP为核心的控制器。利用以上控制系统，在多模态实验平台上进行了吸振器的减振实验研究，结果表明该控制系统能够独立控制磁流变弹性体主动式自调谐吸振器的减振，寻优时间小于15s，并且减振效果良好

Abstract

In order to control automatically an adaptive-active tuned vibration absorber based on magnetorheological elastomers, an algorithm of combining mutative step-size optimization and feedback control was implemented, a controller based on TMS320F2812DSP was designed. Using this control system, the vibration attenuation performance was experimentally investigated on a multi-modal experimental platform. The experimental results show that the controller can control the absorber independently and efficiently in 15 seconds.
