Consensus For Descriptor Multi-agent Systems

With the rapid advancement of technology,artificial intelligence has become an emerging field of the whole world.As a concept with great significance in the field of artificial intelligence,multi-agent systems have been favored by researchers and scientists in recent years.The consensus problem of multi-agent systems is the most classic problem in the field of coordinated control,and its related literature emerges endlessly.Due to the promotion of the above content,the descriptor multi-agent system has also become a hot topic in recent years,and the consensus problem of it has also been favored by many people.However,the consensus problem of descriptor multi-agent systems in the case of exogenous disturbances was rarely mentioned.This thesis took the descriptor multi-agent system with exogenous disturbances as the research object,and focused on its consensus problem.For a descriptor multi-agent system with exogenous disturbances that did not have a leader,we assumed that the disturbances could be modeled using a linear system.Therefore,we first designed the disturbance observer,and then gave the distributed control protocol based on the estimated values and state feedback.At the same time,we gave the conditions for the above distributed control protocol to solve the consensus problem.Finally,numerical simulations were presented to verify the validity of the theoretical results.For a descriptor multi-agent system with exogenous disturbances that included a leader,we assumed that the leader was undisturbed,that the followers were disturbed,and that the disturbances could be modeled with a linear system.Similar to the previous section,we first designed the disturbance observer for the followers.Then,a distributed control protocol was given based on the estimated values,and we gave the conditions to solve this problem under the protocol.Finally,we used a numerical simulation to verify the validity of this conclusion.
