根据载荷设定值的大小，系统根据等比关系将其模糊化成几个区间，并确定当前采集到的载荷的区间号，根据区间的变化赋予采集卡的模拟输出通道一定电压输出到变频器，最终控制电动机的转速，使整个加载过程保持平稳。

Meanwhile, this detected voltage difference is amplified and filtered, and finally the processed signal is transmitted to the analog input of the DAQ card for further software operation, display, and storage.

其工作原理是利用DAQ卡类比输出通道，送出不同频率且幅值恒定的正弦电压信号，透过修正型Howland定电流驱动电路将电压信号转成电流信号加入体内，由量测电极取出电压信号经放大滤波后，把讯号送入类比输入DAQ卡，并在LabVIEW人机介面上做运算处理、分析、显示与储存。
