Iterative learning control of multi-agent systems with random noises and measurement range limitations

In this paper, the iterative learning control is introduced to solve the consensus tracking problem of a multi-agent system with random noises and measurement range limitation. A distributed learning control algorithm is proposed for all agents by utilising its nearest neighbour measured information from previous iterations. With the help of the stochastic approximation technique, we first establish the consensus convergence of the input sequences in almost sure sense for fixed topology as the iteration number increases. Then, we extend the results to switching topologies case which is dynamically changing along the time axis. Illustrative simulations verify the effectiveness of the proposed algorithms.
