    • Controller redesign for delay margin improvement 

      Gündeş, A. N.; Özbay, Hitay (Elsevier, 2020-01)
      Two important design objectives in feedback control are steady-state error minimization and delaymargin maximization. For many practical systems it is not possible to have infinite delay margin andzero steady state error ...
    • Low-order controller design for haptic systems under delayed feedback 

      Liacu, B.; Koru, A. T.; Özbay, Hitay; Niculescu, S. -I.; Andriot, C. (2012)
      In this paper, we consider PD controller design for haptic systems under delayed feedback. More precisely, we present a complete stability analysis of a haptic system where local dynamics are described by some second-order ...
