| Abstract: | Sensor is the core parts in apparatus and measure system,is the most tache in process control. Trans-ducer's output,which is affected by surroundings,directly effect the whole capability. It is significant to improve the sensor's precision. BP neural network is usually used to reduce or eliminate the errors caused by temperature cross sensitivity of pressure sensor. Many algorithms are offered by MATLAB to train BP. Conjugate gradient backpropagation(CGBP),Quasi-Newton algorithms and levenberg-marquardt alg... |
