Synchronization of perturbed Genesio-Tesi chaotic systems via a new finite-time control

, 2018
This paper investigates the synchronization problem for perturbed Genesio-Tesi chaotic system. Based on Lyapnov stability theory, a new finite-time control method is proposed to ensure that the synchronization takes place in finite time.

Novel sensor location scheme using time-of-arrival estimates

, 2012
This study proposes a novel scheme for locating an asynchronous sensor with synchronised beacons using time-of-arrival (TOA) estimates. In this scheme, a reference beacon initiates the localisation by emitting a ranging signal, and the sensor position is
