Embodiment 1

[0044] Such as figure 1 As shown, the upper-level heuristic planning method for multi-star deployment disclosed in this embodiment, the specific implementation steps are as follows:

[0045] Step 1. Establish the mission planning problem model of the upper stage of the rocket.

[0046] The mission planning problem model of the rocket upper stage is represented by a quaternion Φ=(D, I, G, P), where I represents the initial state of the planning problem; G represents the goal of the planning problem; P represents the current part of the plan, which is D is the domain of upper-level mission planning, represented by a triple D=(O,A,C), where O is the collection of deep space detector subsystems, including all subsystems that need to be considered in planning, A C is the set of activities that can be selected by the deep space probe, including all the activities that the probe can perform. The definition of the activity includes time information and other parameters. C is the set ...

Abstract

The invention discloses a multi-star deployment upper-level heuristic task planning method, which belongs to the field of aerospace technology. The method for realizing the present invention is as follows: firstly establish a rocket upper-level task planning problem model, establish a predicate transfer graph according to the planning knowledge model, and calculate the shortest distance between two points in each predicate transfer graph; set the rocket upper-level task planning step step Values, according to the initial partial planning and mission objectives, form a defect set F. Select a defect from the defect set F; select a defect solution method according to the defect type corresponding to the above defect, and solve the defect; repeat the process of selecting defects and solving defects until all defects in the defect set F are resolved or the number of planning steps reaches step value, and finally realize the heuristic mission planning of the upper stage of multi-satellite deployment, and improve the autonomous performance of the upper stage of the rocket. The invention can reduce redundant activities in the planning solution, improve the task planning efficiency of the upper level, and better meet the real-time requirements of the upper level.

Description

technical field [0001] The invention relates to a multi-star deployment upper-level task planning method, which is suitable for planning upper-level tasks in the multi-star deployment process and belongs to the field of aerospace technology. Background technique [0002] The rocket upper stage is a relatively independent one or more stages added to the conventional basic stage launch vehicle, and is an important part of the space transportation system. After being sent into quasi-Earth orbit or Earth orbit by a basic-level carrier rocket, tasks such as gliding, orbital maneuvering, separation and deployment of payloads are completed on the orbit, and finally multi-satellite launch and orbital deployment are realized. The upper stage greatly improves the capability of the launch vehicle and expands the scope of the launch vehicle to perform tasks. Its performance develops according to the changing trend of the payload itself and task requirements. [0003] Traditional upper-...
