摘　　要：针对导弹纵向通道存在干扰影响的问题,设计了一种复合控制方案。首先,选取超螺旋干扰观测器估计未知干扰,并设计积分滑模控制器补偿输入干扰产生的影响;其次,基于微分对策理论,结合自适应动态规划算法,设计单评价神经网络在线求解自适应最优控制器来抑制非匹配干扰,利用Lyapunov稳定性理论证明了闭环系统的稳定性和评价网络权值的收敛性;最后,对导弹纵向动力学进行建模仿真,验证了所提复合控制策略的有效性。A composite control scheme that deals with longitudinal dynamics problems of the missiles suffering from matched and unmatched disturbances is proposed.First,a Super-Twisting Disturbance Observer(STDO) is used to estimate the unknown disturbance,and an Integral Sliding Mode Controller(ISMC) is designed to compensate for the input disturbance.Subsequently,the differential game theory and Adaptive Dynamic Programming(ADP) algorithm are combined to approximate the optimal control by constructing a single critic Neural Network(NN) to counteract the unmatched disturbance online.The stability of closed-loop system and the convergence of the weights of critic network are proved by Lyapunov stability theory.Finally, the effectiveness of the proposed scheme is proved by designing a longitudinal dynamics model of a missile.
