Aiming at the influence of strong non -linearity,strong gyroscopic effect coupling of radial magnetically sus-pended rotor on system stability of magnetically suspended control moment gyroscope,the multichannel non -linearity dynamical model and power amplifier model are built for magnetically suspended rotor.The strong gyroscopic effect coupling of magnetically suspended rotor system is analyzed.The decoupling control method is presented,which com-bines αinverse system with power amplifier link and sliding mode controller,and the simulation test is carried out.The results show that the method has good decoupling effect and robustness for magnetically suspended rotor system.
