摘要
根据合成氨实际生产对转化温度的要求 ,提出了定限值控制问题。初步讨论了采用神经网络控制器 ,来实现定值控制向定限值控制逼近的方法。为提高系统响应的快速性 ,在神经网络内部采用反偏差阈值函数 。
The problem on control of constant-limiting value has been raised in accordance with the requirements of actual synthetic ammonia production to the converting temperature.Thereof,neuron network controller has been adopted after the preliminary study in order for finding out a suitable way to make constant value control approach to constant-limiting value control.For the purpose of increasing the system's response speed,anti-deviation value function has been used in internal neuron network,while duel-mode neuron network control structure has been used in external network.
