Active damping of a DC network with a constant power load: an adaptive passivity-based control approach
Machado, Juan E.; Arocas Pérez, José; He, Wei; Ortega, Romeo; Griñó Cubero, Robert (2018)
Conference lecture
Open AccessThis paper proposes a nonlinear, adaptive controller to increase the stability margin of a direct-current (DC) small-scale electrical network containing a constant power load, whose value is unknown. Due to their negative ... -
An adaptive observer-based controller design for active damping of a DC network with a constant power load
Machado, Juan E.; Ortega, Romeo; Astolfi, Alessandro; Arocas Pérez, José; Pyrkin, Anton A.; Bobtsov, Alexey; Griñó Cubero, Robert (2021)
Article
Open AccessThis article explores a nonlinear, adaptive controller aimed at increasing the stability margin of a direct-current (dc), small-scale, electrical network containing an unknown constant power load (CPL). Due to its negative ... -
On Existence of equilibria of multi-port linear AC networks with constant-power loads
Machado, Juan E.; Griñó Cubero, Robert; Barabanov, Nikita; Ortega, Romeo; Polyak, Boris (2017-10-01)
Article
Open AccessThis paper explores the problem of stability of linear time-invariant (LTI), multi-port AC circuits with instantaneous constant-power loads (CPLs), which model the behavior of some point-of-load converters. It is well-known ...
