D/A转换输出连续性研究

当把D/A输出作为控制系统的输出控制信号时,输出曲线的连续性在很大程度上决定了控制系统的控制精度,细分D/A输出,能够使输出曲线更为连续。介绍了细分D/A输出最小增量使输出曲线更为连续的传统方法,给出了细分D/A输出最小增量的新思路,指出了使用3个D/A转换器,细分连续2个D/A转换输入数据的增量,能使D/A的输出曲线比单个D/A转换器的输出更为光滑连续。

Research into continuity of D/A conversion output

The reason and traditional method of subdividing minimum increment of D/A output for output curve smooth were recommended,while D/A output is regarded as the output control signal. It determines the precision of the control system to a great extent to output the smooth of the curve. It can increase the precision of the control system of subdividing minimum increment of D/A output for output curve smooth.The new thinking of subdividing minimum increment of D/A output was given.Using three D/A converters,through subdividing the increase of two D/A continue input data, the output curve of D/A is smoother than the output of individual D/A converter,and continuity improves greatly.
