According to the fact the output error of angular rate of MEMS gyroscope is nonlinear and fluctuates dramatically with the change of environmental temperature, a temperature compensation method based on fuzzy logic has been presented, in which the u-nitary Takagi-Sugeno fuzzy logic model is adopted for identifying the error model of the gyro bias drift and compensating the error in real-time. The effectiveness of the method has been validated by experiments under two different conditions: the one is the rising of external temperature, and the other is when the gyro is working and heating itself. The results show that the bias stability of MEMS gyroscope can be reduced from 0.01003°/s to 0.007°/s can meet the need of engineering.
