Consensus tracking for multiagent systems with nonlinear dynamics.

Dong R - ScientificWorldJournal (2014)

Bottom Line: This paper concerns the problem of consensus tracking for multiagent systems with a dynamical leader.In particular, it proposes the corresponding explicit control laws for multiple first-order nonlinear systems, second-order nonlinear systems, and quite general nonlinear systems based on the leader-follower and the tree shaped network topologies.Several numerical simulations are given to verify the theoretical results.

fig2: Consensus tracking for the first-order nonlinear systems.

Mentions: In this section, three numerical simulation examples are given to illustrate the theoretical results. Consider the first example, a network of three followers with a leader shown in Figure 1. Assume that the dynamics of the follower agents with n = 2 are described by the following equations:(52)f(t,xi)=(xi1sintxi2cos⁡t),f(t,xr)=(xr1sintxr2cos⁡t).The control input of the leader is given by ur = [1,1]T. Choose βi = 1 for i = 1,2, 3 and ω = 1.5. Note that . The initial values of the error between the multiple followers and the leader, which is described by , i = 1,2, 3, j = 1,2, are given as [0.1, −0.2,0.3, −0.1,0.4,0.2]T. Then the results of consensus tracking are shown in Figure 2, where x1 = [x11, x21, x31]T and x2 = [x12, x22, x32]T. Since as t moves on, consensus tracking is finally achieved.
