提出一种改进的速度扫描M ssbauer谱仪速度控制器。其特点是 :将一般的拾波反馈信号与参考信号串联接入控制器 (串馈 )方式改为两信号并行接入控制器 (并馈 ) ,可方便快速地设定谱仪速度范围 ;引入前馈控制 ,当换能器处于重负荷、高频率、大速度范围等工作状态时能达到较高控制精度。给出了较详细的分析及实验结果。
An improved speed-scanning M ssbauer spectrometer speed controller is proposed. Its features are: the general pickup feedback signal and reference signal in series controller (serial feedback) into two parallel signal access controller (parallel feeding), you can quickly and easily set the spectrometer speed range; the introduction of Feedforward control, when the transducer is in heavy duty, high frequency, high speed range and other working conditions can achieve higher control accuracy. A more detailed analysis and experimental results are given.
