    • Adaptive human pilot model for uncertain systems 

      Tohidi, Shahab; Yıldız, Yıldıray (IEEE, 2019-06)
      Inspired by humans' ability to adapt to changing environments, this paper proposes an adaptive human model that mimics the crossover model despite input bandwidth deviations and plant uncertainties. The proposed human pilot ...

    • Numerical computation of H∞ optimal controllers for time delay systems using YALTA 

      Yeğin, M. O.; Özbay, Hitay (Elsevier B.V., 2016)
      Numerical computation of H∞ controllers for time delay systems has been a challenge since 1980s. Even though significant techniques are developed to obtain direct optimal controllers, application of these methods may require ...

    • Observer based friction cancellation in mechanical systems 

      Odabaş, Caner; Morgül, Ömer (IEEE, 2014-10)
      An adaptive nonlinear observer based friction compensation for a special time delayed system is presented in this paper. Considering existing delay, an available Coulomb observer is modified and closed loop system is formed ...

    • On stabilizing with PID controllers 

      Saadaoui, K.; Özgüler, A. Bülent (IEEE, 2007-06)
      In this paper we give an algorithm that determines the set of all stabilizing proportional-integral-derivative (PID) controllers that places the poles of the closed loop system in a desired stability region S. The algorithm ...

    • Stability analysis of human–adaptive controller interactions 

      Yücelen, T.; Yıldız, Yıldıray; Sipahi, R.; Yousefi, Ehsan; Nguyen, N. (American Institute of Aeronautics and Astronautics (AIAA), 2017)
      In this paper, stability of human in the loop model reference adaptive control architectures is analyzed. For a general class of linear human models with time-delay, a fundamental stability limit of these architectures is ...
