Modeling and simulation analysis of gyrowheel system

Gyro wheel, a new kind of spacecraft attitude control and measurement device, could work as actuators as well as sensors at the same time. With this characteristic, Gyro wheel could reduce the size, mess and cost of the spacecraft attitude control system. It is of great significance for the development of the small satellite. Based on the Euler dynamics equation, the gyrowheel is modeled and both of the mathematical and Adams simulation models are verified. The Adams simulation model is used to simulate four kinds of non-ideal factors in practical conditions. The influence of the four non-ideal factors on gyrowheel motion is obtained through frequency domain analysis of the simulation data, so as to provide a reference for the precision allocation of control system.
