| Abstract: | This paper analyzes nonlinear factors of the differential variable area-change capacitive sensor, and stud- ies the methods of capacitive sensor nonlinear fitting with least square method. And then the paper gives the function of the differential variable area-change capacitive sensor of characteristic curve fitting with least square method. Finally, the experimental error is given between fitting data and measured data. |
