Multi-agent consensus with heterogeneous time-varying input and communication delays in digraphs

no code implementations3 May 2021 Wei Jiang, Kun Liu, Themistoklis Charalambous

First, for all agents whose state matrix has no eigenvalues with positive real parts, a communication-delay-related observer, which is used to construct the controller, is designed for followers to estimate the leader's state information.

Both qubits of the singlet state can be steered simultaneously by multiple independent observers via sequential measurement
