Abstract

This brief mainly investigates the fixed-time attitude stabilization problem for flexible spacecraft subject to inertia uncertainties and external disturbances. First of all, based on active disturbance rejection method, extended state observers and gradient projection estimators are combined to estimate the angular velocity and “total disturbance” of spacecraft simultaneously. Then, a saturation-type controller is constructed, which uses terminal sliding mode technique to achieve fixed-time attitude stabilization. Moreover, a sinusoidal compensating term is added in the controller to solve the singularity problem. Finally, numerical simulations are conducted to illustrate the proposed method.
