Abstract: A kind of fuzzy feedback inferential controller is proposed to the systems whose main output variables are measurable. The controller is derived from the simplification and
improvement of the typical inferential controller, and in which fuzzy logic and inference are used to adjust its filter time constant adaptively. The system performance analyses and simulating experiment results show that the controller has good control performance to the time-delay systems with random disturbances.
Keywords: feedback inferential control, fuzzy logic and inference, filter time constant,
