Sparse Linear Injection Attack on Multi-Agent Consensus Control Systems

This letter investigates the problem of false data injection attack on the communication channels in a multi-agent system executing a consensus protocol. We formulate a non-convex optimisation problem for an attack strategy with minimal one-step attack energy to guarantee instability of the consensus system. We propose an algorithm based on ADMM to solve the problem efficiently in case standard solvers are not available. Numerical simulations are provided to illustrate the effectiveness of the attack strategy.
