Time-varying formation tracking problems for high-order nonlinear multi-agent systems are investigated by using a distributed observer-based method. Different from the previous work, the states of followers form a predefined time-varying formation while tracking the states of the leader with unknown but bounded control input. Besides, the dynamics of each agent is high-order and has nonlinearity....
Practical adaptive time-varying formation tracking problems for second-order nonlinear multi-agent systems are investigated using neural networks, where the time-varying formation tracking error can be arbitrarily small. Different from the previous work, the states of followers form a predefined time-varying formation while tracking the states of the leader with unknown control input. Besides, the...
Practical time-varying formation tracking analysis and design problems for second-order nonlinear multi-agent systems are investigated by using a novel distributed extended state observer, where the formation tracking error can be arbitrarily small. Different from the previous work on formation tracking problems, the states of followers form a predefined time-varying formation while tracking the state...
In this paper, time-varying formation analysis and design problems for second-order nonlinear multi-agent systems are studied using a distributed observer-based method. The formation in this paper can be specified by time-varying continuously differentiable vectors and the dynamics of each agent has nonlinearity. Firstly, a nonlinear time-varying formation control protocol is proposed based on the...
