摘　　要：对于复合侧推力控制的自旋防空导弹,其末端控制时,由于侧喷发动机的工作,动力学特性属于具有离散事件的混杂系统。该文简单介绍了离散事件系统的有限状态机建模方法。利用有限状态机对姿控发动机的离散事件特性建模,同时实现导弹侧推力发动机的推力曲线仿真和复合控制系统仿真模型。由于有限状态机很容易通过仿真软件来实现,因此使用有限状态机能够很方便地建立导弹的一体化仿真环境。文中展示了建立在Simulink环境下的导弹仿真模型,并通过仿真结果展示了控制器的控制效果。A spin anti-air missile with lateral jets is a hybrid system which blended with discrete event when the jets are working in the terminal phase. Modeling method of discrete event system using finite state machine is introduced in this paper. And then the characteristic of lateral jets is modeled by finite state machine. And the curve of thrust and the hybrid controller are also modeled. An integrative simulation environment can be easily established because the finite state machine can be implemented directly in simulation software. Finally, simulation model of the missile which is built in MATLAB/Simulink are displayed at the end of the paper. And simulation results are also displayed to show the performance of controller.
