Limitations of the narrow fuzzy-control and the concept of generalized fuzzy-control

The fuzzy-control usually takes the error and the error derivative between the output and the set point of the system as the input of the controller. But from the pure mathematical point of view, the variable and itpsilas every rank derivative of the system can be seen as the each state of the system. This paper shows some limitation of the classical fuzzy-control and brings forward the concept of generalized fuzzy-control base of the concept of classical fuzzy-control. The concept of generalized fuzzy-control and its application is explained as an example by state feedback based on IFO-KDeltax plus PID in the coordinate control system of power plant.
