    • Adaptive correction and look-up table based interpolation of quadrature encoder signals 

      Ulu, Erva; Geçer-Ulu, Nurcan; Çakmakçı, Melih (ASME, 2012-10)
      This paper presents a new method to increase the available measurement resolution of quadrature encoder signals. The proposed method features an adaptive signal correction phase and an interpolation phase. Typical imperfections ...
    • Combined component swapping modularity for a VCT engine controller 

      Çakmakci, M.; Ulsoy, A.G. (2010)
      The use of bi-directional communication provides additional design freedom which can be used to maximize the swapping modularity of networked smart components. In this paper, application of a design method for combined ...
    • Learning based cross-coupled control for multi-axis high precision positioning systems 

      Geçer-Ulu, Nurcan; Ulu, Erva; Çakmakçı, Melih (ASME, 2012-10)
      In this paper, a controller featuring cross-coupled control and iterative learning control schemes is designed and implemented on a modular two-axis positioning system in order to improve both contour and tracking accuracy. ...
    • On the discrete adaptive posicast controller 

      Abidi, K.; Yildiz, Y. (IFAC Secretariat, 2015)
      In this paper, we present the discrete version of the Adaptive Posicast Controller (APC) that deals with parametric uncertainties in systems with input time-delays. The continuous-time APC is based on the Smith Predictor ...
