recommendations! Published in 2018 at "International Journal of Control, Automation and Systems"

DOI: 10.1007/s12555-016-0730-2

Abstract: In this work, first we estimate all the system’s state vector, with guarantied precision, for a category of second order underactuated mechanical systems (UMS), exploiting the triangular observer (TO) model that suits to the structure… read more here.

DOI: 10.1016/j.ifacol.2020.12.1360

Abstract: Abstract The objective of the present paper is finite-dimensional observer-based control of 1-D linear heat equation with constructive and easily implementable design conditions. We propose a modal decomposition approach in the cases of bounded observation… read more here.

DOI: 10.1016/j.ifacol.2020.12.1863

Abstract: Abstract This paper investigates the extended state observer (ESO) based friction compensation at low velocities with only the position measurement. ESO is an effective model-free friction compensation technique and thus is employed in this paper.… read more here.

DOI: 10.1103/physrevd.96.102005

Abstract: In this paper we provide an experimental illustration of Page and Wootters' quantum time mechanism that is able to describe two-time quantum correlation functions. This allows us to test a Leggett-Garg inequality, showing a violation… read more here.
