Parameterization of All Disturbance Observers for Periodic Input Disturbances
ECTI Transactions on Electrical Engineering, Electronics, and Communications, 2023 In this paper, we examine the parameterizations of all disturbance observers and all linear functional disturbance observers for periodic input disturbances. The plant disturbance observers have been used to estimate the disturbance in the plant. Several papers on design methods for disturbance observers have been published.

A cascade MPC control structure for PMSM with speed ripple minimization [PDF]
, 2013 This paper addresses the problem of reducing the impact of periodic disturbances arising from the current sensor offset error on the speed control of a PMSM. The new results are based on a cascade model predictive control scheme with embedded disturbance

Journal of Fluid Science and Technology, 2014 The laminar-turbulent transition of a mixing layer excited by oscillating flat plates at an exit of a two-dimensional nozzle was experimentally investigated. The mixing layer was formed between the jet issued from the nozzle and the surrounding quiescent

Observer-based tuning of two-inertia servo-drive systems with integrated SAW torque transducers [PDF]
, 2007 This paper proposes controller design and tuning methodologies that facilitate the rejection of periodic load-side disturbances applied to a torsional mechanical system while simultaneously compensating for the observer’s inherent phase delay.
