ABSTRACT:
In a method and apparatus for fuzzy control in contrast to standard methods and arrangements, no sharp quantity is processed as an input quantity of the fuzzy controller; instead, an input quantity is supplied that is affected with a probability density distribution. Thus it is not a sharp value but the probability density distribution of an input value whose membership degree is determined in the inference procedure of the fuzzy controller. This procedure offers advantages, particularly given asymmetrical distribution densities. First, one thus obtains a better response behavior of the controller and, second, the disadvantages that would occur given a pre-filtering of the signal, such as information losses, are avoided.
