A nerve net controller have been designed on the basis of the hardware design of the AC servo system and system model. The controller include two forward nerve net with three layers . One is designed to identify the AC servo system model and another is to control. The controller use special learning algorithm which to control system at the same time and improve its constringency pace through introducing new MFBP algorithm. The intelligent control algorithmic is programmed using C++ language after the controller have been designed .

在该交流伺服系统硬件设计和系统数学建模的基础上，设计了神经网络自适应控制器，这个控制器包括两个三层的前馈神经网络，一个神经网络用于非线性系统的辨识，另一个神经网络作为控制器，此控制器采取边学习边控制的工作方式，并采用一种新型的MFBP算法实现了控制算法的快速性，在控制器设计完成的基础上，利用C++语言具体实现智能控制算法的编写。

由于神经网络技术的发展，神经网络在非线性控制方面显示出强大的优势，同时近年来出现的逆系统方法对于多变量非线性系统的控制指出了一条可算是光明的道路，鉴于以上两项技术的优越性，本文提出对BMPS进行神经网络逆系统控制的方法，首先通过机理分析的方法建立了BMPS的非线性动态数学模型，并依此模型设计了神经网络逆系统控制方案，由于此方案中需要用到球磨机磨筒内负荷的反馈，但是磨内负荷是一个不能直接测量的量，而且其测量方法是多年来人们一直在努力的方向却又一直不能较好地解决，本文提出对其进行神经网络测量的思想和方法，这一方法的仿真试验和现场实测结果均表明其研发造价低廉的优越性和测量较为准确的实用性。

Positive nerve fibers are in pedal nerve cords and visceral nerve cords. There are no neuronal nitric oxide synthase or inducible nitric oxide synthase positive cells or fibers in the nervous system. A few of endothelial nitric oxide synthase strongly positive nerve cells are identified in pedal ganglia and visceral ganglia. Weakly positive cells and nerve fibers of eNOS can be seen in all of the ganglia and nerve cords.
