Resilient Distributed State Estimation for LTI Systems

  title={Resilient Distributed State Estimation for LTI Systems},
  author={Aritra Mitra and Shreyas Sundaram},
Consider a linear time-invariant (LTI) dynamical system monitored by a network of sensors, modeled as nodes of an underlying directed communication graph. We study the problem of collaboratively estimating the state of the system when certain nodes are compromised by adversarial attacks. Specifically, we consider a Byzantine adversary model, where a compromised node possesses complete knowledge of the system dynamics and the network, and can deviate arbitrarily from the rules of any prescribed… CONTINUE READING
