摘　　要：对弹道导弹的三通道非线性模型进行了分析,为了实现三通道的解耦设计,简化控制系统结构,将通道间的耦合项和干扰项看作是单个通道的不确定项,从而将非线性模型转化为一种解耦形式。在此基础上,采用自适应模糊滑模控制方法设计了弹道导弹的推力矢量控制系统。自适应模糊滑模控制方法利用自适应模糊控制器来调节滑模控制参数,对不确定项的边界进行估计和补偿,保证了系统的跟踪误差指数地收敛到零。仿真结果表明了该控制方法的有效性。The three channel nonlinear models of ballistic missile are analyzed. The couple terms among three channels and disturbance terms are regarded as uncertain terms of single channel, in order to realize decoupled design for three channels and to simplify the control system structure. On the basis of it, an adaptive fuzzy sliding mode control （ AFSMC ） method is applied to design the thrust vector control system of ballistic missile. In the AFSMC method, adaptive fuzzy controller adjusts the parameter of sliding mode controller to estimate and compensate the bound of uncertainties, which guarantees that the system tracking error converges to zero exponentially. Simulation results show the validity of the AFSMC method.
