摘　　要：针对中制导段飞行时间长,空间拦截器需要进行一定的姿态机动,提出一种基于RBF网络的姿态控制器。建立了拦截器3个通道的姿态运动模型,对每个通道进行变结构控制,并在此基础上对变结构控制器增益通过RBF(RadialBasis Function)网络进行自适应控制,同时给出了稳定性证明。仿真结果表明,该方法能有效实现拦截器中制导段的姿态控制。An attitude controller based on RBF network is presented for large maneuver angles in long-time midcourse phase. After the models of the attitude movement in three subsystems are constructed, the variable structure controller is applied to each subsystem and its gains are tuned by RBF （Radial Basis Function ） network. Moreover, the stabilization of the attitude system is proved. Simulation results show that this method can implement the midcourse attitude control effectively.
