Distributed SAR satellite formation has been widely studied and applied because of its unique advantages, and beam synchronization is the prerequisite for achieving its function. An inverse optimal control method is proposed for the ideal nominal system in this paper, which is based on two beam synchronization strategies of Doppler guidance and beam pointing synchronization. And on this basis, considering the influence of satellite communication delay, external disturbance and system model uncertainty, an integral sliding mode robust control method based on inverse optimal control is designed. The simulation results show that the control method has high control accuracy and good robustness.
