Errors Dynamics in Affine Group Systems
Xinghan Li, Jianqi Chen, Han Zhang +2
Errors dynamics captures the evolution of the state errors between two distinct trajectories, that are governed by the same system rule but initiated or perturbed differently. In p…
Geometrical Characterization of Sensor Placement for Cone-Invariant and Multi-Agent Systems against Undetectable Zero-Dynamics Attacks
Jianqi Chen, Jieqiang Wei, Wei Chen +3
Undetectable attacks are an important class of malicious attacks threatening the security of cyber-physical systems, which can modify a system's state but leave the system output m…
Multi-agent deployment under the leader displacement measurement: a PDE-based approach
Jieqiang Wei, Emilia Fridman, Anton Selivanov +1
We study the deployment of a first-order multi-agent system over a desired smooth curve in 3D space. We assume that the agents have access to the local information of the desired c…
