Mutlu, Barış Ragıp
In this thesis, novel implementation methods for FPGA based real-time motion control systems are investigated. These methods are examined for conventional and modern controller topologies as well as peripheral device interfaces which are mutually essential pieces of a motion controller. The developed methods are initially tested one by one to assess the performance of the individual design; and finally an assembled solution is developed to test the overall design. Tests of the overall design are realized via hardware-in-the-loop simulation of a real-world control problem, selected as a CNC machining center. The developed methods are discussed in terms of their success, resource consumptions and attainable sampling rates.

Prediction of slip in cable-drum systems using structured neural networks
KILIÇ, Ergin; Dölen, Melik (SAGE Publications, 2014-02-01)
This study focuses on the slip prediction in a cable-drum system using artificial neural networks for the prospect of developing linear motion sensing scheme for such mechanisms. Both feed-forward and recurrent-type artificial neural network architectures are considered to capture the slip dynamics of cable-drum mechanisms. In the article, the network development is presented in a progressive (step-by-step) fashion for the purpose of not only making the design process transparent to the readers but also hig...
Vibration-based damage identification in beam-like composite laminates by using artificial neural networks
Şahin, Melin (SAGE Publications, 2003-01-01)
This paper investigates the effectiveness of the combination of global (changes in natural frequencies) and local (curvature mode shapes) vibration-based analysis data as input for artificial neural networks (ANNs) for location and severity prediction of damage in fibre-reinforced plastic laminates. A finite element analysis tool has been used to obtain the dynamic characteristics of intact and damaged cantilever composite beams for the first three natural modes. Different damage scenarios have been introdu...
CFD analysis of a notebook computer thermal management solution
Yalçın, Fidan Seza; Tarı, İlker; Department of Mechanical Engineering (2008)
In this study, the thermal management system of a notebook computer is investigated by using a commercial finite volume Computational Fluid Dynamics (CFD) software. After taking the computer apart, all dimensions are measured and all major components are modeled as accurately as possible. Heat dissipation values and necessary characteristics of the components are obtained from the manufacturer's specifications. The different heat dissipation paths that are utilized in the design are investigated. Two active...
Development of a micro-fabrication process simulator for micro-electro-mechanical systems(mems)
Yıldırım, Alper; Dölen, Melik; Department of Mechanical Engineering (2005)
The aim of this study is to devise a computer simulation tool, which will speed-up the design of Micro-Electro-Mechanical Systems by providing the results of the micro-fabrication processes in advance. Anisotropic etching along with isotropic etching of silicon wafers are to be simulated in this environment. Similarly, additive processes like doping and material deposition could be simulated by means of a Cellular Automata based algorithm along with the use of OpenGL library functions. Equipped with an inte...
Uncertainty analysis of coordinate measuring machine (CMM) measurements
Sözak, Ahmet; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2007)
In this thesis, the measurement uncertainty of Coordinate Measuring Machine (CMM) is analysed and software is designed to simulate this. Analysis begins with the inspection of the measurement process and structure of the CMMs. After that, error sources are defined with respect to their effects on the measurement and then an error model is constructed to compensate these effects. In other words, systematic part of geometric, kinematic and thermal errors are compensated with error modelling. Kinematic and geo...
