搭建了基于MATLAB／Simulink的一类非线性、时变靶弹全弹道动态仿真框架，基于该框架完成了高度模糊，线性复合控制系统设计。研究结果表明：1）基于MATLAB／Simulink的靶弹全弹道动态仿真具有结构清晰、效率高、可调性和重复性好的优点；2）所设计的靶弹高度模糊／线性复合控制系统能适应靶弹较大空域的变化，并能较好抑制阶跃干扰、推力变化的影响，具有良好的预定高度跟踪性能。

All trajectory dynamics simulation framework for an nonlinear and time-variant target missile using the MATLAB/Simulink software was established. The design of altitude fuzzy/linear combined control system was completed based on this simulation framework. The results show that： 1） All trajectory dynamic simulation based on MATLAB/Simulink software for target missile has several advantages such as clear structure, high efficiency, good adjustability and repetitiveness; 2） Designed altitude fuzzy/linear combined control system of target missile adapts to large airspace change of target missile, restrains the impact of stepped jamming and thrust change, and has good predetermined altitude tracking performance.
