Euler-Lagrange multi-agent system, backstepping control, Terminal virtual error surface
This paper presents a distributed terminal (finite-time) backstepping consensus control for multi-agent Euler-Lagrange systems. Terminal virtual error surfaces and virtual controls are proposed to guarantee the finite-time error consensus and formation convergence of a group of one-leader and multi-follower cooperative tracking Euler-Lagrange system.Finite-time stability including infinite-time stability was proved by the finite-time Lyapunov candidate function. Simulation example shows the effectiveness of the proposed finite-time backstepping coordinated tracking controller.
