WANG Zheng-hong1, MA Yi-wu1, CHEN Jian-qun1. Non-linear calibration of thick film pressure sensor based on BP neural network[J]. 2007, (2): 82-84. DOI: 10.13873/j.1000-97872007.02.028.
The structure and mechanics model of thick film pressare sensor
traditional non-linear calibration’s methods and the theory of non-linear calibration with artifical neural network(ANN)are introduced.The model of thick-film pressure sensor’s non-linear calibration with BP neural network is discussed
and the program is emulated by ANN toolbox in MATLAB.The result indicates that the non-linear calibration of elasticity strain and pressure in the mothed can decrease 2 magnitude of the standard error and sensor’s non-linear calibration is effectively actualized.
