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

, 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

Integrated fault estimation and accommodation design for discrete-time Takagi-Sugeno fuzzy systems with actuator faults [PDF]

, 2011
This paper addresses the problem of integrated robust fault estimation (FE) and accommodation for discrete-time Takagi–Sugeno (T–S) fuzzy systems. First, a multiconstrained reduced-order FE observer (RFEO) is proposed to achieve FE for discrete-time ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Fuzzy control of a sailboat

International Journal of Approximate Reasoning, 1997
AbstractThis paper describes a combined helm-sails controller for a sailboat based on fuzzy logic. Autonomous navigation of sailboats is a very nonlinear and time-variant problem, and modeling ship dynamics considering all real phenomena is a very complex task.

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Composite Fuzzy-Based Control Strategy for Uncertain Underactuated System

IEEE Access
Most practical systems are influenced by disturbances and uncertainties within their models, increasing the need for robust control algorithms. Type-2 fuzzy theory and its variant, interval type-2 fuzzy, are well-regarded for their capability to ...
