摘　　要：针对航天器姿态控制执行机构磁悬浮控制力矩陀螺的高速大惯量飞轮转子系统的强非线性和由强陀螺效应产生的进动和章动导致系统的失稳问题,提出了模糊控制和传统的PID和交叉解耦控制相结合的方案,对高速转子系统中非线性所导致的问题进行了研究。研究表明,该控制器解决了陀螺效应导致的主动磁轴承-高速大惯量飞轮转子的不稳定性问题,且抑制了噪声对磁轴承稳定性的影响。最后,数值算例证明了该方法的可行性和有效性。The association scheme of Fuzzy control and Classical PID and cross decouping control was proposed on the strong nonlinear and Gyro effective and instability of AMB--high speed and large inertial moment Flywheel rotor system of magnetically suspended control moment gyro for attitude control of spacecraft. At the same time, the problem caused by nonlinear in high speed and large inertial moment rotor system was studied. It is shown that the controller can solve the instability problem of flywheel rotor and restrain the influence of the system that noise causes. The simulation is used to verify the effectiveness and feasibility of the proposed method.
