Research on the Signal of Silicon Micro-Machined Gyroscope for Rotating Carrier

In the research on the gyroscope, itpsilas an important problem to get the deflexion direction and the deflexion angle of the rotating carrier with the signal of gyroscope. This paper makes a detailed discussion of an envelope integral method for getting deflexion angle, and also gives a introduction to the issue of getting deflexion direction in the phase method. In order to get deflexion direction, the signal of gravity acceleration-meter as reference is needed and then comparing the signal of the gyroscope and gravity acceleration-meter, the phase difference will be figured out. At last, the deflexion direction can be made out by the phase difference. Using MCU to find out the peak value of the gyroscope signal, and then do integral to time, the deflexion angle can be counted out.
