Abstract:

Aiming at the target assignment for on orbit operation of distributed satellites system (DSS), a target assignment method based on particle swarm optimization (PSO) is proposed. The target assignment model for on orbit operation is built by taking DSS’s minimum maneuver energy as an objective function. Based on fixed time interception theory, an optimal maneuver scheme characterized by maneuver time and velocity increment of a single satellite is realized. PSO is applied to solve the problem by designing correspondence relation between particle position and target assignment solution, and the algorithm steps are expatiated. The analysis results of two examples show that the model and the algorithm can get feasible and accurate solution quickly, which can efficiently resolve the multi constrained target assignment for on orbit operation.
