| Abstract: | The paper proposes principle and method of multiplication curve matching. High languages of computer are made use of getting curve coefficienrs of matching functions for magnetic field of sensor with temperature and for magnetic field with non-linearity output respectively. The coefficients of matching functions get by counting.As the coefficient is established, the curve of matching function can be set up. Non-linearity error and temperature error of magnetic sensors are compensated. Feasibility of the method is validated by experiment. |

| Keywords: | least quadric multiplication curve matching non-linearity error compensation temperature error compensation |
