This paper briefly introduces the working principle of silicon micro-mechanical vibrating wheel gyroscope, and gives the nonlinear equations and linear equations of motion of the gyroscope. Aiming at the gyroscope’s equation of motion, numerical simulation is carried out. According to the numerical simulation results, it is also suggested that closed-loop control must be adopted in order to improve the linearity of measurement. At the same time, it also gives a closed-loop control program.
