Chattering free adaptive sliding mode control for attitude tracking of spacecraft with external disturbance
In this paper, the attitude tracking problem of spacecraft in the presence of unknown disturbance is investigated. By using the adaptive control technique and Lyapunov stability theory, a chatteringExpand

Fuzzy isomorphism theorems of soft rings
The concepts of fuzzy ideals of soft rings are introduced. The first, second and third fuzzy isomorphism theorems of soft rings are established respectively. In particular, some classes of quotientExpand

Quantifying touch–feel perception: tribological aspects
We report a new investigation into how surface topography and friction affect human touch–feel perception. In contrast with previous work based on micro-scale mapping of surface mechanical andExpand

Design and control methodology of a 3-DOF flexure-based mechanism for micro/nano-positioning
A 3-DOF (X-Y-?Z) planar flexure-based mechanism is designed and monolithically manufactured using Wire Electro-Discharge Machining (WEDM) technology. The compact flexure-based mechanism is directlyExpand

A revisit to a class of permutation quadrinomials
Abstract This paper revisits the quadrinomials x 3 q + a 1 x 2 q + 1 + a 2 x q + 2 + a 3 x 3 over F q 2 , where q is a power of 2. We propose a more comprehensive characterization of the coefficientsExpand
