Model-based control design for H2 purity regulation in high-pressure alkaline electrolyzers
(2021-05-01)
Article
Restricted access - publisher's policyThis paper proposes two control strategies that mitigate the cross contamination of H2 and O2 in a high-pressure alkaline electrolyzer, which consequently increases the supplied gases purity: one based on a decoupled PI ... -
Disturbance observer-based LPV feedback control of a N-DoF robotic manipulator including compliance through gain shifting
(2021-10)
Article
Open AccessThis paper proposes a control scheme for a -DoF robotic manipulator in a joint-regulation motion problem, dealing with disturbances (as e.g. exogenous forces, unmodelled dynamics) that hinder task fulfilment, and also ...
