摘　　要：为了实现对一种机械式自调谐吸振器的减振控制,设计了以TMS320F2812为主处理器的控制器和以L298N为核心的驱动器,结合变步长寻优控制算法开发了LabVIEW人机界面。利用这套控制系统,在多模态实验平台上进行该吸振器的减振控制实验,结果表明控制系统能够实现对吸振器的嵌入式控制,并且控制过程可实时观测。In order to control a mechanical adaptive tuned vibration absorber（MATVA） automatically, a controller based on a main processor of TMS320F2812 and a driver based on L298N were designed, an algorithm of mutative stepsize optimization was used to develop a LabVIEW human-machine interface. Using this control system, the absorber vibration attenuation performances were experimentally investigated on a multi-modal experimental platform. The experimental results showed that the absorber can be controlled independently and efficiently with the control system, and the control process is real-time observable.
