BP neural network modeling is introduced using MATLAB neural network toolbox function, In order to find the non-linear mathematical model between data. And process parameters is optimized combination the neural network and genetic algorithm, The method has been applied to optimize parameters for nitric acid device, and proved to be highly importance, Programming with MATLAB is very brief and practicable to optimize parameters using neural network and genetic algorithm.
It will be face some problems about the complicated reaction mechanism, environment uncertainty, serious nonlinear in nitric acid process .a method of creating steady-state model of nitric acid process using neural network. and used genetic algorithm to optimize parameter on neural network model. The result can provide reference for analyzing and optimizing the parameters of nitric acid process.
This article introduced a mathematical model consist in data of system in Bp neural network. An artificial neural network modeling is constituted to use MATLAB neural network toolbox function .The method has been applied in nitric acid process of some plant, and proved to be highly effective.
Nitric acid production process is complicated reaction mechanism, serious non-linear the traditional mechanism modeling to get the low accuracy of the mathematical model. This paper adopts a non-mechanism modeling, using the production history data, the use of artificial neural network has the right to arbitrary nonlinear mapping any approximation ability to simulate the relationship of the actual system input-output, trained to be get steady-state model of the nitric acid production process.
The paper introduced the method and technology of how to implement a Integrated Manufacturing, each CNC machining equipment is equipped with a special communication unit, each communication unit are directly connected with the DNC main control computers on the Internet, effect of special communication unit is mainly data buffer and protocol conversion, the TCP/IP protocol is used between communication unit and DNC main control Internet computer, and used serial communication protocol communication between communication unit and NC equipment. Using this technology, all kinds of CNC machining equipment and DNC system can be easily with the CAD/CAM/CAE system, digital profile measurement system, fault diagnosis and error compensation of intelligent system integration, providing good technical conditions for further information of various advanced manufacturing environment integration.
