Event-triggered Relative Position Coordinated Control for Spacecraft Formation with Limit Communication

摘要

This paper presents an event-triggered coordinated control for spacecraft formation to achieve the formation configuration with limit communication. First, to reduce the communication burden, a state-dependent triggered function is provided with the position and velocity of each spacecraft. The triggered condition is determined by monitoring measurement errors. Then, under the undirected communication topology, an adaptive coordinated control scheme is proposed for formation system with uncertainties and disturbances. Zeno behaviour is excluded by theoretical analysis. Finally, simulation result is performed to illustrate the effectiveness of the designed scheme.
