Development of fuzzy controllers with non-homogeneous dynamics for integral-type plants

  • R.-E. PrecupEmail author
  • S. Preitl


The paper proposes a systematic development method for fuzzy controllers with non-homogeneous dynamics with regard to the input channels (of reference input and controlled output), and 14 versions of fuzzy controllers. A sensitivity analysis of the developed fuzzy control systems with respect to controlled plant parametric variations is performed. The development method and controllers are validated by two case studies that can correspond to electrical drives speed control.
