Qi Wu, Tan Hou, Yuanlong Li, Liangren Shi · 2020
Semi-global output consensus problem of multi-satellite systems described by characteristic model is addressed in this paper. In this system, we consider the follower satellites subject to actuator saturation and external disturbances. Based on the low-gain feedback method and modified algebraic Riccati equation (MARE), we propose a distributed consensus algorithm such that under a connected communication graph and a reachable leader, the follower satellites can achieve semi-global output consensus when using the proposed algorithm. The effectiveness of this method has been substantiated in the simulation part.
