The Triaxial Angular Rate Measurement System Based on Two MEMS Accelerometers Used for Rotating Carrier

Abstract:

Considering that the MEMS Gyroscope used in rotating carrier has the problems of small range and low measurement accuracy, the tri-axial angular rate measurement system based on two MEMS accelerometers used for rotating carrier was presented in this paper. The system has the advantages of large measurement range, anti-high overload, simple structure, small volume and low price. From the principle of the tri-axial angular rate measurement system, the mathematical model of the system was established and the mechanics model of the system was discussed. The different processing method of the output signal in each condition was summarized based on the mechanics model. Finally, the semi-physical simulation experiment was done to verify these theories. The experimental results show that the system scheme is feasible and has obvious advantages in the range and measurement accuracy.
