An alternative electrospinning approach with varying electric field for 2-d-aligned nanofibers
(IEEE, 2014-01)In the electrospinning process, unstructured nanofiber mats are produced by oriented fluid jets with an external electrostatic field. Electrospun fibers have wide applications for the fabrication of composite materials, ... -
Backstepping robust h-infinity control for a class of uncertain switched nonlinear systems under arbitrary switchings
(Wiley, 2013-01)This paper addresses global robust H 8 control for a class of switched nonlinear systems with uncertainty under arbitrary switchings. Each subsystem is in lower triangular form. The uncertainties are assumed to be in a ... -
Boundary control of a rotating shear beam with observer feedback
(SAGE Publications, 2012)We consider a flexible structure modeled as a shear beam which is free to rotate on the horizontal plane. We first model the system by using partial differential equations and we propose boundary feedback laws to achieve ... -
Continuous-time Hopfield neural network-based optimized solution to 2-channel allocation problem
(TÜBİTAK, 2015-03-20)The channel allocation problem in cellular radio systems is NP-complete, and thus its general solution is not known for even the 2-channel case. It is well known that the link gain system matrix (or received-signal power ... -
Controllability and stabilizability of a class of continuous piecewise affine dynamical systems
(Society for Industrial and Applied Mathematics, 2014)This paper studies controllability and stabilizability of continuous piecewise affine dynamical systems which can be considered as a collection of ordinary finite-dimensional linear input/state/output systems, together ... -
Decentralized adaptive synchronization of an uncertain complex delayed dynamical network
(Springer, 2009-08)In this paper, we investigate the locally and globally adaptive synchronization problem for an uncertain complex dynamical network with time-varying coupling delays based on the decentralized control. The coupling terms ... -
Discrete pseudo-SINR-balancing nonlinear recurrent system
(Hindawi Publishing Corporation, 2013)Being inspired by the Hopfield neural networks (Hopfield (1982) and Hopfield and Tank (1985)) and the nonlinear sigmoid power control algorithm for cellular radio systems in Uykan and Koivo (2004), in this paper, we present ... -
Efficient energy scavengers by flexible robot arm with non - uniform cross - section
(IET, 2012)The vibration-based energy scavenger consists of beams with piezoelectric layers and proof mass, is usually designed by single-link or cantilever beam configurations. In order to overcome inherent problems, for example, ... -
Fast - convergent double - sigmoid hopfield neural network as applied to optimization problems
(IEEE, 2013-06)The Hopfield neural network (HNN) has been widely used in numerous different optimization problems since the early 1980s. The convergence speed of the HNN (already in high gain) eventually plays a critical role in various ... -
Feedback passivation of switched nonlinear systems using storage-like functions
(Springer, 2011-10)This paper addresses the issues of passivity and feedback passivation of switched nonlinear systems via multiple storage functions. The concept of storage-like functions for switched systems is presented. A sufficient ... -
Finite-time regulation of two-spool turbofan engines with one shaft speed control
(The American Society of Mechanical Engineers, 2016-08)Nonlinear control of aircraft engines has attracted much attention in consideration of the inherent nonlinearity of the engine dynamics. Most of the nonlinear design techniques, however, require the information from the ... -
Homing air-defence missile systems using a novel fuzzy-logic mode of fire control
(University of Niš, 2008)Problem pogađanja ciljeva u vazduhu je prilično kompleksan zadatak u kome je svaki raketni system za odbranu iz vazduha odgovoran za upravljanje paljbe. U ovom radu predstavljamo novi pristup i modus za upravljanje paljbe ... -
Influence of the state space partitioning into regions when designing switched fuzzy controllers
