Fuzzy control in the presence of signal distributions

The paper deals with signal distributions interpreted as fuzzy signals in the control loop, With respect to specific effects coming up with the use of sensory information like noise or spatial distribution of a signal it is of interest how the control loop behaves in the presence of fuzzy signals. Instationary fuzzy sets, especially time variant membership functions and their derivatives, are described. Furthermore, in the context of fuzzy inputs the control schemes of sliding mode fuzzy control and Takagi/Sugeno (1985) control are discussed
