The hardware principle diagram is given. The methods of decreasing the overshoot and increasing the control precision during controlling the temperature are described in details.

给出了硬件原理图，并详细介绍了温度对象控制过程中克服滞后、减小超调量提高控制精度的方法。

In addition, since a temperature variation, that is, overshoot or undershoot, of the heating roller is reduced, a fixing efficiency can be increased.

此外，由于减少了加热辊的温度变化即过冲或下冲，所以可提高图像的定影效率。
