Disturbance Rejection And Tracking Of Multi-agent System Under Sliding Mode Control With Event-driven Strategy

Derived from the study of the group activities of the living nature,the research on the multi-agent systems has experienced tens of decades,and it has been now applied in areas as aviation,energy,power and so on.In contrast to the control of an individual subject,the control on multi-agent system show us not only a more simplified and flexible process,but also an optimized and reliable outcome,so it is worthy of research and significance.Scholars have predicted that multi-agent systems are likely to make contributions in those cross-frontier environments such as transportation,communication,networks etc.As a typical nonlinear control method,the sliding-mode control strategy has been handled very skillfully in the controlling world.Many a way that conducted by switch control is widely embraced by mechanical and chemical industry among these years.Apart from this,the event-driven strategy is playing an all-important role in the study of multi-agent systems currently for its irreplaceable advantages in saving resources of space and information.Multi-agent system covers a wide range and owns a profound meaning,however,it will be faced with influences from communication and noises.Therefore,how to settle the questions caused by disturbances and the system uncertainty,as well maintain a stable and efficient operation of the system simultaneously has become the key to experts' exploration.Under the construction of dual auxiliary states,this article consider the consistence of multi-agent system which is bothered by outside disturbance that is bounded firstly.Event-driven strategy is employed and a sliding-mode is established for the purpose to restrain the disturbance.Based on that,a leader-following multi-agent system is discussed.By means of improving the followers' control protocol,the former system is able to follow the leader's state under the circumstance of interference existing,so that the whole system will achieve the objective of tracking as well as remain globally consistent.Theoretical proof has been displayed drawing support from mathematics to demonstrate all the conclusions and there is no Zeno behavior by this means of event-driven method.Lastly,the simulation sample in Matlab proves the validity of the previous theories.
