| Abstract: | BP neural network in artificial neural network (ANN) is adopted to process gas sensor array signal. An artificial olfactory system, which is composed of a gas sensor array with the pattern recognition technique of a feed forward neutral network, is designed to make quantative analysis of the gas mixture. The simulation of non-linear gas sensor array has been made by use of computer simulation method, and BP artificial neural network has been designed by MATLAB neural network toolbox to process and compare the simulation data. The results show that the method of ANN has good non-linearity, approximation ability and high discrimination ratio. |
