This article explores the leader-following consensus tracking(LFCK) control issues of multi-agent systems(MASs)in the presence of external disturbances and general directed fixed communication topology. Its purpose is to enable all follower agents to achieve consensus tracking for the leader agent. Firstly, this article introduces an extended state observer for estimating each follower agent's unknown state and external disturbance. Subsequently, on the basis of the above-extended state observer and a dynamic event-triggered strategy, a distributed consensus tracking control protocol with disturbances restraint is developed,which can reduce the MAS's update frequency on the premise of ensuring the control protocol's effectiveness. Furthermore,the MAS's stability and the absence of Zeno behavior are analyzed and proved by the established Lyapunov functional and linear matrix inequality theory. Finally, the validity and feasibility of the proposed approach are validated through a group of comparative numerical simulation experiments.

Dear Editor,Phenotypic drug discovery,which observes compound effects on physiology,has given way to targeting specific molecules,but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al.,2022).Osteoarthritis(OA)is a prevalent chronic joint disorder,primarily affecting knee joints,with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).This imbalance and the discharge of inflammatory mediators perpetuate the cycle of inflammation and tissue ***,controlling inflammation and modulating osteoclastogenesis are critical therapeutic targets for managing OA.
