【摘要】 本文研究了斯特林制冷机中采用单机减振的控制系统的设计问题。由于振动主要是由持续的可测干扰源引起,因此采用了基于自适应滤波的前馈控制方案。最后用以DSP为核心的控制器,成功的将某型斯特林制冷机的振动水平降低了一个数量级,表明了控制的有效性。更多还原

【Abstract】 In this paper the active vibration control of Stirling cryocooler is studied. Because the durative disturbance which result in vibration can be measured. Feedforward Control arithmetic based on LSM adaptive filter is adopted.The control arithmetic is realized by the DSP(digital signal processor).The vibration amplitude of the Stirling cryocooler is damped lower to one tenth of the original amplitude after the active vibration control is used.更多还原
