In the current paper, time-varying formation tracking (TVFT) problems for second-order multi-agent systems with external disturbances are studied. Based on active disturbance rejection controller, a robust TVFT protocol is proposed, which contains compensation. To restrain influence of disturbances, an extended state observer designed to estimate compensation using control input and output information system. For case that desired trajectories known, approach give stationary transient...

Political identity is an important cornerstone for the development of a country or nation. Embarking on new road catching up, it still necessary to gather majestic strength unity and struggle among all ethnic groups. Junior high school students as graduating students, this stage explore also test results first two years teaching. In paper, we go into field investigate educational status junior in Sandong Middle School Guizhou causes behind quo, put forward corresponding paths enhance...

Adaptive guaranteed-performance formation analysis and design problems for second-order multi-agent systems are studied, where the global information is not required, which means main results of this article fully distributed. First, an adaptive control protocol presented systems, input constructed using neighboring state errors adaptively adjustable interaction weights. Then, proposed based on Riccati inequalities. Furthermore, cost determined adjusting approach gain in terms linear matrix...

Guaranteed-performance formation control for swarm systems with the second-order dynamics is investigated based on synchronization strategy. Firstly, a new protocol presented, where weights of connected edges are adaptively regulated and performance constraint imposed. Then, basis Riccati inequality, sufficient conditions synchronization-based guaranteed-performance proposed, an explicit expression cost shown, it fully distributed to design gain matrices in sense that independent global...
