YU Ya-ting. Nonlinear errors compensation method of eddy current sensor based on BP neural network[J]. 2007, (10): 54-56. DOI: 10.13873/j.1000-97872007.10.023.
The eddy current sensor improves the relativity between the sensor’s probe and the measured object
but the serious nonlinearity is appeared.To compensate the nonlinear errors
the BP network is adopted.The result is compared with that from the fitting function method.The result indicates that the two methods both can improve the linearity of the sensor.However
the compensation curve from BP network is smoother and the linearity of the sensor is better.
