Fault detection for uncertain LPV systems using probabilistic set-membership parity relation
(2020-03-01)
Article
Restricted access - publisher's policyThis paper considers fault detection of uncertain linear parameter varying systems that have polynomial dependence on parametric uncertainties. A conventional set-membership (SM) approach is able to ensure zero false alarm ... -
A non-centralized predictive control strategy for wind farm active power control: A wake-based partitioning approach
(Elsevier, 2020-05-01)
Article
Open AccessOwing to wake effects, the power production of each turbine in a wind farm is highly coupled to the operating conditions of the other turbines. Wind farm control strategies must take into account these couplings and produce ... -
Dynamic modelling of alkaline self-pressurized electrolyzers: a phenomenological-based semiphysical approach
(2020-01-01)
Article
Restricted access - publisher's policyThis paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen ...
