Under the sea: How can we use heart rate and accelerometers to remotely assess fish welfare in salmon aquaculture?
(Peer reviewed; Journal article, 2023)Recent advances in bio-sensing technologies open for new possibilities to monitor and safeguard the welfare of fishes in aquaculture. Yet before taken into practice, the applicability of all novel biosensors must be ... -
Underactuated leader-follower synchronisation for multi-agent systems with rejection of unknown disturbances
(Journal article, 2015)In this paper leader-follower synchronization is considered for underactuated followers in an inhomogeneous multi-agent system. The goal is to synchronise the motion of a leader and an underactuated follower. Measurements ... -
Underactuated mechanical systems: Whether orbital stabilization is an adequate assignment for a controller design?
(Peer reviewed; Journal article, 2020)The paper contributes to developing algorithms for motion planning and motion control for mechanical systems with two and more passive degrees of freedom by exploring a challenging example in details. As shown, some of ... -
Understanding Instantaneous frequency detection: A discussion of Hilbert-Huang Transform versus Wavelet Transform
(Chapter, 2017)Nonlinear and/or nonstationary properties have been observed in measurements coming from microgrids in modern power systems and biological systems. Generally, signals from these two domains are analyzed separately although ... -
Understanding the Nonlinear Behaviour and Synchronizing Stability of a Grid-Tied VSC Under Grid Voltage Sags
(Chapter, 2019)Transients of a typical grid synchronizing VSC are closely associated with the over-current and over-voltage in circuits. Previous analysis in evaluating such transient phenomenon usually ignore the nonlinear control effects ... -
Understanding the Origin of Oscillatory Phenomena Observed between Wind Farms and HVDC Systems
(Journal article; Peer reviewed, 2016)Field experience has shown that sub-synchronous oscillation (SSO) and harmonic resonance can occur between wind farms (WFs) and high voltage dc (HVDC) systems. The oscillations can appear in the presence of background ... -
