摘　　要：针对嫦娥五号飞行程序多舱段、多任务、系统控制复杂的设计特点和难点,采用传统的飞行程序设计方法工作量大,状态控制困难,很难满足任务要求。提出了一种新的基于状态转移的方法对飞行程序进行系统建模,首先将整个飞行过程分解成若干模块状态机;然后针对每个模块状态机的功能划分为状态触发器、评估器、执行器和确认器,并分别开展建模设计;最后通过状态触发器和确认器将各个功能模块进行连接,形成整个飞行程序的有限状态机描述。相比传统方法,该方法具有通用性、可扩展性和可复用性等特点,对于规范飞行程序设计,描述复杂的飞行任务过程有很大的优势。采用该方法对嫦娥五号飞行程序进行了建模和设计,并给出了典型飞行过程的设计结果。在轨飞行试验结果表明,该方法可以满足飞行任务的要求,确保了嫦娥五号在轨飞行控制任务圆满成功。In view of the design characteristics and difficulties of Chang'e-5 flight program,such as multi-cabin,multi-target and complex system control,the traditional flight program design method is difficult to meet the mission requirements due to its heavy workload and difficult state control.In this paper,a new method based on state transition was proposed for system modeling of flight program.The whole flight process was firstly decomposed into several module state machines,then each module state machine was divided into state generator,state assessor,command executor and state verifier according to their functions,and modeling design was carried out respectively.Finally,each function module was connected by state generator and state verifier to form the finite state machine description of the whole flight program.Compared with traditional methods,this method has the characteristics of generality,extensibility,reusability,and has great advantages in standardizing flight program design and describing complex flight mission process.The flight program of Chang'e-5 was modeled and designed by using this method,and the design results of typical flight process were given.The in-orbit flight test results show that this method can meet the requirements of the mission and ensure the successful in-orbit flight control of Chang'e-5 mission.
