Experimental validation of a continuous-time MCSI algorithm with bounded adaptive gains
(2019-08-01)
Article
Restricted access - publisher's policyModel reference adaptive control algorithms with minimal controller synthesis have proven to be an effective solution to tame the behaviour of linear systems subject to unknown or time-varying parameters, unmodelled dynamics ... -
Decoupled inputs sliding mode controllers for a fuel cell-supercapacitor module in hybrid generation applications
(Springer, 2019-01-01)
Article
Open AccessThe development of Multiple Input/Multiple Output (MIMO) sliding mode control setups for a fuel cell/supercapacitor module is presented in this paper. The main objective of the proposed controllers consists in simultaneously ... -
Robust sliding mode control of a DC/DC Boost converter with switching frequency regulation
(2018-01-01)
Article
Restricted access - publisher's policyThis paper presents the design of a hysteresis band controller to regulate the switching frequency in a sliding mode controlled nonlinear Boost power converter. The proposed architecture relies on a piecewise linear modeling ... -
Fixed-switching frequency interleaved sliding mode eight-phase synchronous buck converter
(Institute of Electrical and Electronics Engineers (IEEE), 2018-01-01)
Article
Open AccessThis paper describes the design of an interleaved sliding mode control for a multiphase synchronous buck converter, which inherits the properties of sliding mode control, operates with fixed switching frequency in the ... -
Lie symmetries of nonrelativistic and relativistic motions
(American Physical Society (APS), 2019-03-15)
Article
Open AccessWe study the Lie symmetries of non-relativistic and relativistic higher order constant motions in d spatial dimensions, i.e. constant acceleration, constant rate-of-change -of-acceleration (constant jerk), and so on. In ... -
Comprehensive high speed automotive SM-PMSM torque control stability analysis including novel control approach
(2019-07-01)
Article
Restricted access - publisher's policyPermanent magnet synchronous machines (PMSM) are widely used in the automotive industry for electric vehicle (EV) and hybrid electric vehicle (HEV) propulsion systems, where the trend is to achieve high mechanical speeds. ... -
Robust admittance shaping approach to grid current harmonic attenuation and resonance damping
(2018-09-01)
Article
Open AccessThis paper presents a novel grid current control of a grid-connected voltage source converter with an LCL filter. The proposed control method uses an H 8 synthesis method to shape the input admittance of the converter, to ... -
Complex-based controller for a three-phase inverter with an LCL filter connected to unbalanced grids
(Institute of Electrical and Electronics Engineers (IEEE), 2018-07-09)
Article
Open AccessA new controller for a grid connected inverter with an LCL filter is proposed in this paper. The system is described by its complex representation and the controller is designed using the complex root locus method. The ... -
Port-hamiltonian based optimal power flow algorithm for multi-terminal DC networks
(2019-02-01)
Article
Restricted access - publisher's policyIn this paper an algorithm for solving the Optimal Power Flow problem for multi-terminal DC networks based on the gradient method is proposed. The aim is seeking the optimal point subject to voltage, current and power ... -
Stabilisation of state-and-input constrained nonlinear systems via diffeomorphisms: A Sontag's formula approach with an actual application
(2018-09-10)
Article
Open AccessIn this work, we provide a new and constructive outlook for the control of state-and-input constrained nonlinear systems. Previously, explicit solutions have been mainly focused on the finding of a barrier-like Lyapunov ... -
Active damping: an Hinf model reference approach
(Institute of Electrical and Electronics Engineers (IEEE), 2018-08-01)
Article
Open AccessThis paper focuses on the design of an active-damping controller that shapes the dynamics of an LCL grid connected voltage source converter (VSC) to mimic an L-filter connected VSC. This makes possible to use simpler ... -
Reducing the cogging torque effects in hybrid stepper machines by means of resonant controllers
(Institute of Electrical and Electronics Engineers (IEEE), 2018-06-11)
Article
Open AccessPermanent magnet machines are not free from the interaction between magnets and the stator and rotor slots, which causes an undesired disturbing torque. Such cogging or detent torque is especially larger with salient pole ...
