铍青铜真空时效炉快速升温模型及自适应方法

The Rapid-risen Temperature Model and Adaptive Control Method fot the Beryllium Bronze Vacuum Time-effective Furnace

校青铜真空时效炉是热处理专用设备。对于温度控制，它是非线性系统。按其工艺要求，在到达设定组应前，炉内温度必须尽可能快速上升，但不允许出现超调现象。设备还要求控制方法能自动适应显著不同的初恋和不同的装炉量。本文给出了用于快速升温的数学模型和自适应控制方法，较好地满足了工艺和设备的要求。该模型和控制方法可用于解决类似问题。

The vacuum time affective furnace is a'special instrument for heat treating of Be - Bronge Alloy. It is a nonlinear system for temperature control. At the requirement of technological process the temperature uf furnace must rise as quickly as possible before arriving at the rating given and, however, outstrip must be avoided. In this paper a mathematical model and a control method are presented, which put the requirement int0 effect and is adaptable to great different initial state of the furnace temperature and different quantity of work - piece. The model and control method can be applied to resolve the similar control problems.
