Abstract: For the problem of abnormal position control, which is produced by separation of measure and control, in the existing attitude control system, a spacecraft attitude angular rate method based on magnetically suspended control moment gyroscope is proposed. A dynamic model of magnetically suspended control moment gyroscope with pyramid configuration is established, and the integrated measurement and control mechanism of spacecraft based on magnetically suspended control moment gyroscope is analyzed according to the theorem of inertia moment. An analytical expression of attitude angular velocity is obtained through joint solution of 3 magnetically suspended control moment gyroscopes in pyramid configuration . Simulation results verify the correctness and superiority of this method.

Key words: control science and technology, measurement of attitude angular rate, magnetically suspended control moment gyroscope, theorem of inertia moment, analytical solution
