Robust PID Control for Robot Manipulators with Parametric Uncertainties
(Belgrade: ETRAN SocietyBelgrade : Academic Mind, 2018)
Most of the industrial robots use a classical PIDtype
controller for positioning tasks. A main reason for this is its
effectiveness in regulation tasks, simple linear structure, and
easy implementation. Moreover, it is ...
Determination of critical size of corrosion pit on mechanical elements in hydro power plants
(Udruženje intelektualaca za razvoj nauke u Srbiji, Novi Sad, 2018)
Researchers in the field of fracture mechanics, predominantly developing appropriate solution algorithms for problems of solid bodies with cracks. Problems in mechanics generally, related with fracture and fatigue for solid ...
Let na Mars - simulacija anvelope u centrifugi visokih performansi na zemlji / Flight to Mars: Envelope simulation in a ground based high-performance human centrifuge
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Ovo istraživanje ima za cilj da doprinese slanju prve ljudske posade na Mars. U radu je simulirana anvelopa leta na Marsa u centrifugi visokih performansi. Visoka G-opterećenja prilikom poletanja, iskustvo nulte i ...
A model for evaluation of customer satisfaction with banking service quality in an uncertain environment
(Routledge Journals, Taylor & Francis Ltd, Abingdon, 2018)
The aim of this study was to propose a fuzzy decision-making model to evaluate customer satisfaction level which has a critical effect on the bank's competitive advantage and its business. Value of customer satisfaction ...
Analysis of the Laser Forming of Shaped Surfaces Using the Adaptive Neuro-fuzzy Technique
(Old City Publishing, 2018)
Three-dimensional (3-D) shape modelling from a flat sheet by lasers needs numerous irradiations along surface paths with different parameters of heating. In this study it was attempted to form a three-dimensional shaped ...
Reliability Estimation of Stochastic Dynamical Systems with Fractional Order PID Controller
(World Scientific Publ Co Pte Ltd, Singapore, 2018)
In this paper, the reliability of stochastic dynamical systems under Gaussian white noise excitations with fractional order proportional-inegral-derivative (FOPID) controller is estimated. First, the FOPID controller is ...
Effect of temperature and exploitation time on tensile properties and plain strain fracture toughness, K-Ic, in a welded joint
(Elsevier Science Bv, Amsterdam, 2018)
Effect of temperature and exploitation time on resistance to brittle fracture of welded joint constituents of new and 40 years exploited low-alloyed Cr-Mo steel A-387 Gr. B has been analysed. The plane strain fracture ...
Integrity assessment of turbine flat cover pipe
(Institut za ispitivanje materijala, Beograd, 2018)
The turbine flat cover pipe (dimension phi 219.1x12.7 mm, and material STPG-38) is tested and cracks are found. Determination of the required wall thickness for a pipe exposed to internal pressure is done according to EN ...
Stochastic modelling of three-dimensional particle rebound from isotropic rough wall surface
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
This paper describes an extension of the two-dimensional approach to particle-rough wall collision modelling (Sommerfeld and Huber, 1999; Konan et al., 2009) to the case of three-dimensional particle rebound from an isotropic ...
Enhanced control of radiator heating system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
In this paper a radiator heating system of a building is considered. For the purpose of the heating system optimization, a mathematical model of the system is developed. The linear quadratic algorithm with integral action ...
