Abstract:

Aiming at the problem of ground verification of spacecraft proximity operation algorithms and pursuit-evasion in close range, a three degrees-of-freedom (3-DOF) microgravity floating simulator is developed, and the pursuit strategy and evasion strategy based on potential function introducing virtual boundary obstacles are proposed. The proposed method makes use of the properties of potential function effectively to avoid obstacles in the environment while pursuing evader and constrains the motion in the limited ground space. The experimental results show that the pursuer can pursue the evader, and is consistent with the simulation results, and proves that the experimental platform can be used to test the maneuver control algorithm and also verifies the effectiveness of the proposed pursuit and evasion strategy based on potential function.

Key words: floating simulator, potential function, pursuit-evasion strategy, virtual obstacle
