A finite-time fully distributed consensus (FTFDC) control problem is studied for a second-order multiagent system (MAS) with input saturation, limited communication resources and external bounded disturbances. Firstly, to deal with the input saturation characteristics, a second-order auxiliary system is designed to obtain the compensation signal. Secondly, because the leader information can only be obtained by a group of agents connected with the leader, a distributed estimator for each agent is designed to estimate the leader information. Then, to save communication resources, an event trigger condition is designed without continuous communication between agents. Based on the estimator and event trigger condition, a FTFDC controller is designed to realize the finite time fully distributed consensus control of MAS under limited communication resources and external bounded disturbances. Finally, the designed controller is verified by simulation on a multi-spacecraft attitude system model.
