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

Çakmakcı, Melih; Ulsoy, A.G. (ASME, 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. ...
