未知对象 meaning in English

unknown object

First , it applies fuzzy logical in the abstract and non - linear dealing ability ; second , it applies neural net in the self - study and any functions approaching ability ? through combining above two ability , it can find a best p i d non - linear controlling regularity and achieve controlling on line of the unknown subject etco therefore , it not only can strengthen robust and intelligence of the system , but also make design simple and easily be requiredo in addition , the thesis also does many works on procedure of upper - computer and basic - controller and the whole system designed can be put into work immediately
根据啤酒发酵过程具有大惯性、时滞和非线性等特点，本论文还提出一种基于神经网络的模糊自适应pid控制方案，它一方面利用模糊逻辑的“概念”抽象能力和非线性处理能力，另一方面利用神经网络的自学习能力和任意函数的逼近能力，通过两者的有机结合寻找一个最佳的p 、 i 、 d非线性组合控制规律，以实现对未知对象进行在线控制，并具备适应控制环境变化的能力和自学习能力等。
