YU A-long · Microcomputer Information · 2010
A method used to the capacitance weighing sensor non-linearity compensation is applied based on wavelet neural network(WNN) to settle its non-linear problem.In this method,a non-linear compensation network can be set up according to measurement data of capacitance weighing sensor.The compensating principle is introduced and the geometrical structure of the network is analyzed and the algorithms of network parameters training is given.The results show that the proposed WNN has strong robustness,and on-line correction ability,and fast network training speed and high precision when used in the capacitance weighing sensor non-linearity compensation and practical value in measurement field.
