Finite control set model predictive control with feedback correction for power converters

open access: yesCES Transactions on Electrical Machines and Systems, 2018
As an open-loop model predictive control algorithm, finite control set model predictive control (FCS-MPC) scheme in power converter system is based on assumption that responses of optimal control implemented on prediction model agree well with actual ...

Non mean-field behavior of the contact process on scale-free networks [PDF]

open access: yes, 2006
We present an analysis of the classical contact process on scale-free networks. A mean-field study, both for finite and infinite network sizes, yields an absorbing-state phase transition at a finite critical value of the control parameter, characterized ...

An Improved Finite Control Set Model Predictive Current Control for a Two-Phase Hybrid Stepper Motor Fed by a Three-Phase VSI

open access: yesEnergies, 2022
In this paper, an improved finite control set model predictive current control (FCS-MPCC) is proposed for a two-phase hybrid stepper motor fed by a three-phase voltage source inverter (VSI). The conventional FCS-MPCC selects an optimal voltage vector (VV)

Algebraic synthesis of time-optimal unitaries in SU(2) with alternating controls [PDF]

open access: yes, 2014
We present an algebraic framework to study the time-optimal synthesis of arbitrary unitaries in SU(2), when the control set is restricted to rotations around two non-parallel axes in the Bloch sphere. Our method bypasses commonly used control-theoretical

Unbounded Viscosity Solutions of Hybrid Control Systems [PDF]

open access: yes, 2008
We study a hybrid control system in which both discrete and continuous controls are involved. The discrete controls act on the system at a given set interface.

Finite-Time Controllability and Set Controllability of Impulsive Probabilistic Boolean Control Networks [PDF]

open access: yesIEEE Access, 2020
This paper addresses the finite-time controllability and set controllability of impulsive probabilistic Boolean control networks (IPBCNs). Firstly, using the algebraic state space representation (ASSR) method, the transition probability matrix of IPBCNs is established.

Maximum Energy Capturing Approach for Heaving Wave Energy Converters Using an Estimator-Based Finite Control Set Model Predictive Control

open access: yesIEEE Access, 2021
The control problem in wave energy continues to remain an open question. This is mainly attributed to the difficulties associated with developing effective, yet economically viable, wave energy-harnessing control strategies, such as resource irregularity,
