Vibration Reduction of the Nonlinearly Tufted Carpet Yarn by a Modified Sliding Mode Control Method

open access: yesShock and Vibration, 2019
The yarn vibration causes the yarn tension value to fluctuate, causing a change in the amount of yarn feed, thus causing a deviation of the carpet pile height from the predetermined value. To solve this problem, the sliding mode control algorithm is used

Discrete-time output feedback sliding-mode control design for uncertain systems using linear matrix inequalities [PDF]

open access: yes, 2011
An output feedback-based sliding-mode control design methodology for discrete-time systems is considered in this article. In previous work, it has been shown that by identifying a minimal set of current and past outputs, an augmented system can be ...

Hybrid fuzzy and sliding-mode control for motorised tether spin-up when coupled with axial vibration [PDF]

open access: yes, 2009
A hybrid fuzzy sliding mode controller is applied to the control of motorised tether spin-up coupled with an axial oscillation phenomenon. A six degree of freedom dynamic model of a motorised momentum exchange tether is used as a basis for interplanetary
