摘要
Satellites with large rotating components may accomplish some specific scientific missions and have attracted a great deal of research interests. This paper investigates the control problem of such satellites. The model of the rotating component is carefully studied and both the static and dynamic unbalance are analyzed and demonstrated. To achieve a high precision control with unbalance rejection, a sliding mode control strategy is proposed. Practical simulations are conducted to verify the effectiveness of the proposed controller and simulation results illustrate that both the static and dynamic unbalance are perfectly compensated and a high-precision control is achieved.
