Abstract: Intelligent adaptive control of spacecraft is an important part of intelligent autonomous control for spacecraft．In this paper，by taking the spacecraft with deployable and retractable flexible appendage as the object，the principle and method of intelligent adaptive control are researched SO as to realize the control target of high precision，high stability and strong adaptability．According to the characteristic model and the golden section adaptive control law，a parameter varying active adaptive control method based on the length of the flexible appendage is presented．This method combines the control of center rigid body with the active control of appendage．Numerical simulations show that by applying the parameter varying active adaptive control，the vibration of the attitude angle and modes can be rapidly suppressed and the overshoots are very small when the appendage deploys，retracts or is excited by resonance disturbances and that the designed controller excels other controllers．
