在自动控制中,非线性器件是很多的,特别是传感器件,如热敏元件、压敏元件、力敏元件、湿敏元件等等.它们之中的大多数输出电量值与被测物理量值呈非线性关系.在控制电路中,一种常用的方法是使用线性放大器,在输出端进行逐段线性化(其总体即为一个非线性放大器).虽然这不失为一种有效的方法,但线性化的精度及稳定性都会受到较大限制. 近年来,数字电路已相当普及,利用可编程存贮器作非线性校正,不但可限制温度的影响,而且还可提高校正精度.本文就EPROM电路在数字式温度调节器中的应用,阐述该类电路作非线性校正用的几个问题. In the automatic control, a lot of nonlinear devices, especially sensor devices, such as thermal sensors, pressure sensitive components, force sensitive components, humidity sensors, etc. Most of them output power value and the measured physical value A non-linear relationship In the control circuit, a commonly used method is to use a linear amplifier, the output of the piece by piece linearization (which is generally a non-linear amplifier.) Although this is an effective method, but the linear In recent years, digital circuits have become quite popular, the use of programmable memory for non-linear correction, not only to limit the impact of temperature, but also improve the accuracy of correction.In this paper, EPROM circuit In the digital temperature regulator application, elaborated on this kind of circuit for non-linear correction of several problems.
