Leader-Following Consensus for Second-Order Nonlinear Multiagent Systems with Input Saturation via Distributed Adaptive Neural Network Iterative Learning Control

Abstract EN

In this paper, the consensus tracking control problem of leader-following nonlinear multiagent systems with iterative learning control is investigated.

The model of each following agent consists of second-order unknown nonlinear dynamics and the external disturbance.

Moreover, the input of each following agent is subject to saturation constraint.

It is assumed that the information of leader is not available to any following agents, and the radial basis function neural network is introduced to approximate the nonlinear dynamics.

Then, a distributed adaptive neural network iterative learning control protocol and the adaptive updating laws for the time-varying parameters are proposed, respectively.

A new Lyapunov function is constructed to analyze the validity of the presented control protocol.

Finally, a numerical example is provided to verify the effectiveness of theoretical results.
