Comments on Digital Current Control in a Rotating Reference Frame-Part I: System Modeling and the Discrete Time-Domain Current Controller With Improved Decoupling Capabilities
(Institute of Electrical and Electronics Engineers, 2018-05-28)
A recent paper presents a discrete time model in a rotating dq reference frame of an R-L filter, and its current control. The purpose of this note is: 1) To show that the discrete model presented in the paper behaves ...
Robust Local Stabilization of Discrete-Time Systems with Time-Varying State Delay and Saturating Actuators
(Hindawi Publishing Corporation, 2018-07)
The robust local stabilization of uncertain discrete-time systems with time-varying state delayed and subject to saturating actuators is investigated in this work. A convex optimization method is proposed to compute robust ...
Microcellular Electrode Material for Microbial Bioelectrochemical Systems Synthesized by Hydrothermal Carbonization of Biomass Derived Precursors
(American Chemical Society, 2016-05)
A new monolithic carbonaceous material, 750-HMF-CarboHIPE, is presented here. The new electrode has been tested as an anode material inside a microbial bioelectrochemical system. In a purposely designed continuous flow ...
Sliding mode neuro-adaptive controller designed in discrete time for mobile robots
(Acta Press, 2018-04)
It is well known that all robotic systems have additional dynamics and disturbances beyond those that are modelled. Hence, in this paper, the performance of a neuro-adaptive sliding mode control (NA-SMC) controller is ...
Nonlinear MPC for Tracking Piece-Wise Constant Reference Signals
(Institute of Electrical and Electronics Engineers, 2018-11)
This paper presents a novel tracking predictive controller for constrained nonlinear systems capable to deal with sudden and large variations of a piece-wise constant setpoint signal. The uncertain nature of the setpoint ...
Interpolation for gain-scheduled control with guarantees
(Pergamon-Elsevier Science Ltd, 2011)
State Measurement Error-to-State Stability Results Based on Approximate Discrete-Time Models
(Institute of Electrical and Electronics Engineers, 2019-08)
Digital controller design for nonlinear systems may be complicated by the fact that an exact discrete-time plant model is not known. One existing approach employs approximate discrete-time models for stability analysis and ...
