An Integration method over a moving window for exponential convergence in adaptive control without persistency of excitation
Yayla, Metehan; Kutay, Ali Türker; Department of Aerospace Engineering (2016)
Adaptive control has great capabilities in control of uncertain systems to maintain a consistent and desired performance. Another control methodology concerning the uncertain systems is the robust control. It is well-known that the robust control has advantages of dealing with external disturbances, unmodeled dynamics, and quickly varying uncertain parameters. Nonetheless, robustness against these environmental, and parametric uncertainties degrades the tracking performance. Besides, adaptive control can to...
Modeling and control of a heated tank system with variable liquid hold-up
Yücel, Tarık; Kıncal, Serkan; Department of Chemical Engineering (2013)
The aim of this thesis study was the modeling and controlling of a heated tank system with variable liquid hold-up. Mathematical model representation of the process was developed using mass and energy balances. Experiments were conducted to obtain the correct model parameters of the process. After obtaining the model parameters, linearized form of the model was developed. Proportional-Integral-Derivative (PID) controller parameters are found at different nominal conditions using a Simulink code that estimat...
A bdi-based multiagent simulation framework
Yükselen, Murat; Polat, Faruk; Department of Computer Engineering (2008)
Modeling and simulation of military operations are becoming popular with the widespread application of artificial intelligence methods. As the decision makers would like to analyze the results of the simulations in greater details, entity-level simulation of physical world and activities of actors (soldiers, tanks, etc) is unavoidable. In this thesis, a multiagent framework for simulating task driven autonomous activities of actors or group of actors is proposed. The framework is based on BDI-architecture w...
Using ontology based web usage mining and object clustering for recommendation
Yılmaz, Hakan; Karagöz, Pınar; Department of Computer Engineering (2010)
Many e-commerce web sites such as online book retailers or specialized information hubs such as online movie databases make use of recommendation systems where users are directed to items of interests based on past user interactions. Keyword-based approaches, collaborative and content filtering techniques have been tried and used over the years each having their own shortcomings. While keyword based approaches are naive and do not take content or context into account collaborative and content filtering tech...
A Control System Architecture for Control of Non-Affine in Control, Open-Loop Unstable Underactuated Systems
Marangoz, Alp; Kutay, Ali Türker (2017-07-25)
In this paper, a control system architecture for control of non-affine in control, open-loop unstable underactuated system is discussed. Passivization of the unactuated (internal) system dynamics achieved through perturbation of trajectories of the actuated states, which are calculated through adaptive dynamic inversion technique, based on Tikhonov's theorem. Performance of the controller is shown through simulation of two open-loop unstable and locally uncontrollable example problems.
