• Describing Function Method for PI-Fuzzy Controlled Systems Stability Analysis 

      Precup, Radu-Emil; Preitl, Ştefan ("Dunarea de Jos" University of Galati, 2004)
      The paper proposes a global stability analysis method dedicated to fuzzy control systems containing Mamdani PI-fuzzy controllers with output integration to control SISO linear / linearized plants. The method is expressed ...
    • On a Takagi-Sugeno Fuzzy Controller with Non-Homogenous Dynamics 

      Precup, Radu-Emil; Preitl, Ştefan ("Dunarea de Jos" University of Galati, 2001)
      The paper proposes a Takagi-Sugeno fuzzy controller with non-homogenous controller dynamics with respect to the two input channels, that means, in the linear case, different transfer functions with respect to the reference ...
