Disturbance Observer-Based Frequency Regulation for Shipboard Microgrid With Communication Delay

open access: yesIEEE Access, 2023
Load frequency control of power systems is inherently a disturbance rejection issue. This paper proposes a disturbance observer-based frequency regulation approach for a shipboard microgrid system with communication delay.

Simple disturbance observer for disturbance compensation

open access: yesIET Control Theory & Applications, 2010
Disturbance observer (DOB) without using additional sensors is an attractive method to attenuate the effects of disturbances as they are highly cost effective. This study proposes a simple form of DOBs, which does not need to solve the plant model inverse, and uses H∞ control method to design the Q-filter in the DOB.

Delay compensation for nonlinear teleoperators using predictor observers [PDF]

open access: yes, 2010
This paper presents a delay compensation technique for nonlinear teleoperators by developing a predictor type sliding mode observer (SMO) that estimates future states of the slave operator. Predicted states are then used in control formulation.

DC Bus Voltage Control of Wind Power Inverter Based on First-Order LADRC

open access: yesIEEE Access, 2022

Observer based tuning techniques and integrated SAW torque transducers for two-inertia servo-drive systems [PDF]

open access: yes, 2005
A controller design and tuning methodology is proposed that facilitates the rejection of periodic load-side disturbances applied to a torsional mechanical system, whilst simultaneously compensating for the disturbance observer's inherent phase delay ...

Disturbance observers and applications [PDF]

open access: yesTransactions of the Institute of Measurement and Control, 2016
The control performance of practical systems has inevitably suffered from various disturbances and uncertainties, including external environmental disturbances, unknown model uncertainties (possibly caused by unmodelled dynamics) and parameter perturbations.
