Predictor-Based Collision-Free and Connectivity-Preserving Resilient
Formation Control for Multi-Agent Systems under Sensor Deception Attacks
Abstract
Malicious attack is a potential threat for collision-free and
connectivity-preserving formation control. In this paper, a
predictor-based collision-free and connectivity-preserving resilient
formation control strategy is presented for a class of nonlinear
multi-agent systems under sensor deception attacks. The predictor states
are designed to replace original states in the control strategy, and a
novel attack compensator is constructed to suppress sensor deception
attack. Prediction errors, instead of compromised errors, are introduced
to update radial basis function neural networks (RBFNNs) weights. To
achieve collision avoidance and connectivity preservation, a
transformation function in logarithmic form is proposed. To avoid static
and dynamic obstacles, an improved artificial potential function (APF)
combined with their velocity information is constructed. Furthermore, to
solve the local minimum in the combining of transformation function and
APF, a virtual force is added to make agents get away. Based on the
Lyapunov stability criterion, all closed-loop signals are bounded and
all control objectives can be achieved. The simulation of a group of
quadrotors has verified the effectiveness of the proposed resilient
control strategy.
