Li-ying Xu, Lijun Li · 2011
The relationship between output voltage and the loading of the capacitance weighing sensor is nonlinear. To obtain accurate measurement, it is necessary to compensate the nonlinearity. A nonlinear compensation method based on Neural Networks with Orthonormal Functions is proposed in this paper. The convergence of the neural network algorithm is researched. The result shows that the method proposed has high accurate. Therefore, the method proposed is effective and may be used for other applications.
