    Robust Output Tracking Control of an Unmanned Aerial Vehicle Subject To Additive State Dependent Disturbance
    (Institution of Engineering and Technology, 2016) Tanyer, İlker; Tatlıcıoglu, Enver; Zergeroglu, Erkan; Deniz, Meryem; Bayrak, Alper; Özdemirel, Barbaros
    In this study, an asymptotic tracking controller is developed for an aircraft model subject to additive, state-dependent, non-linear disturbance-like terms. Dynamic inversion technique in conjunction with robust integral of the sign of the error term is utilised in the controller design. Compared to the previous studies, the need of acceleration measurements of the aircraft have been removed. In addition, the proposed controller design utilises only the output of aircraft dynamics. Lyapunov based analysis is applied to prove global asymptotic convergence of the tracking error signal. Numerical simulation results are presented to illustrate the performance of the proposed robust controller.

    Design of an Experimental Twin-Rotor Multi-Input Multi-Output System
    (John Wiley and Sons Inc., 2015) Bayrak, Alper; Doğan, Fırat; Tatlıcıoğlu, Enver; Özdemirel, Barbaros
    Twin-rotor multi-input multi-output system (TRMS) is a popular experimental setup utilized mostly for development and evaluation of aerovehicle control algorithms. Motivated by its popularity, construction steps of a TRMS setup in an academic setting are presented in this paper. Specifically, design of mechanical and electronic hardware components and development of related computer software are described in detail. Preliminary experiment results are also presented to demonstrate the performance of the system. © 2015 Wiley Periodicals, Inc.

    On-Line Educational Tool for the Parallel Operation of the Synchronous Generators
    (John Wiley and Sons Inc., 2011) Bekiroğlu, Erdal; Bayrak, Alper
    This study presents a PC and a PIC microcontroller based an on-line educational tool for the monitoring and controlling of the parallel operation of the synchronous generators. The presented tool measures the voltages, the frequencies, the phase sequences, and the synchronism time data of the generators through microcontroller. The measured data, the voltage graphics, and the status of the parallel operation conditions are monitored on the computer instantaneously. The parallel operation of the generators is controlled with the developed tool automatically. The educational tool is user-friendly, real-time, reliable, and precise. © 2009 Wiley Periodicals, Inc.
