In diesem Beitrag wird die Anwendung zeitkontinuierlicher rekurrenter Fuzzy-Systeme (KRFS) zur Modellbildung technischer Systeme beschrieben. Ausgehend von der Systembeschreibung rekurrenter Fuzzy-Systeme werden Verfahren vorgestellt, mit denen das KRFS das Verhalten des Prozesses anhand von Messdaten und qualitativem Prozesswissen erlernen kann. Die(More)
This paper presents a novel approach to the control of compressor systems used for the supply of fuel gas to gas turbines in combined cycle power plants. A model for the compression system is derived first and special attention is paid to an accurate description of the compressor map. Due to the strong coupling of the nonlinear dynamics of the compression(More)
This paper presents a novel approach to the control of fast operating point transitions of compression systems for gas turbines. A nonlinear model of the compression system is derived and shown to be flat. Based on the flatness property a feedforward control for a two-degree of freedom controller is designed, which permits fast transitions between operating(More)
In recent years, a concise theory of recurrent fuzzy systems has emerged and methods for utilizing these fuzzy systems with dynamics for modeling and fault detection were developed. At the same time, sum of squares decompositions in conjunction with semidefinite programming were successfully applied for the synthesis of controllers for polynomial systems.(More)
