Flow Disturbance Compensation Based on Off-Line Estimated Signal for a Pneumatic Isolation Table
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013 The flow disturbance to a pneumatic vibration isolation table causes periodic fluctuation of the table. In current study, one cycle of flow disturbance is estimated offline using a disturbance observer.

Dual-Period Repetitive Control for Nonparametric Uncertain Systems With Deadzone Input
IEEE Access, 2019 In this paper, a dual-period repetitive control scheme is proposed to accomplish the periodic trajectory tracking task for a class of nonparametric uncertain systems with deadzone nonlinear input, and there is no common multiple between the period length

Composite control of single-phase inverter based on SRFPI and reduced-order LADRC
Energy Reports, 2023 One of the development trends of inverters is toward higher performance. Periodic and non-periodic disturbances will result in excessive harmonic distortion in the output voltage and reduce the performance of single-phase inverters.

Dynamics of entanglement in a two-dimensional spin system [PDF]
, 2011 We consider the time evolution of entanglement in a finite two dimensional transverse Ising model. The model consists of a set of 7 localized spin-1/2 particles in a two dimensional triangular lattice coupled through nearest neighbor exchange interaction
