摘要：
A measurement and control integrated method of spacecraft attitude based on magnetically suspended control moment gyroscope (MSCMG) of pyramid configuration is proposed. The actuator in attitude control loop is used to measure and control spacecraft attitude, thus breaking the traditional attitude control loop which is composed by attitude sensor, controller, actuator. The radial torque model of the magnetic suspension rotor is established firstly, real-time detect magnetic bearing current, magnetic suspension rotor displacement and the frame angular velocity in MSCMG, get spacecraft attitude angular velocity through simultaneous three radial torque model in pyramid configuration. Then the control law of attitude and steering law of framework is designed to realize spacecraft attitude regulation. The simulation results show the effectiveness and superiority of this method. © 2016, Chinese Institute of Electronics. All right reserved.
