Adaptive partition method of improving sensor's nonlin ear using neural networks

ZHU Qingbao(Dept of Computer Sci,Nanjing Normal University, Nanjing 210097,China)  
A method that the inverse function of sensor's characteristic is identified with adaptive partition using neural netw orks.Using this method,the inverse function of sensor's characteristic can be partitioned into many intervals with adaptive method according to requis ition of learning accuracy using BP neural networks,and the interval function is learned and identified in the each interval respectively using a BP neural net work,after that,the each BP neural network replace the corresponding inverse fun ction in the each interval,and the sensor characteristics linearization are real ized.The results of simulations and application have shown that the nonlinear er rors of the sensor are decreased nine tenths using this method.
