GUO Quan-min, WANG Jian. Nonlinear correction of methane sensor based on functional link neural network[J]. 2008, 27(10): 5-7. DOI: 10.13873/j.1000-97872008.10.019.
The nonlinear relation between methane volume fraction and catalytic methane sensor output voltage is indicated by analysis of the sensor detection principle.A nonlinear correction model based on functional link neural network(FLNN)
which is characterized by nonlinear approach ability and independent on accurate mathematical model
is proposed to eliminate the nonlinear errors in methane detection.The comparison between simulation result and piecewise linear fitting curve shows that the model has advantageous of simple structure
