摘要： 利用折线方程确定和代替信号传递函数，并通过软件方法求得近似传递函数的反函数；然后运用反函数实现信号的线性提升，达到降低信号测量非线性误差的目的。此方法在笔者研制开发的“YWS96-B型烟叶复烤机控制系统”上进行了实践和验证，收到较好的效果。

Abstract: Using the equation of broken line to define and substitutes for the signal transfer function, and the inverse function of approximate transfer function is obtained by way of the software method. Then the application inverse function is realized promoting of signal linearity, and achieves the purpose that reduces the nonlinearity to measure the signal error.This method developed on "YWS96-B's mould tobacco leaf is repeatedly baked the control system " having carried on the practice with verifying, and being received better effect.
