Abstract: The present invention relates to the architecture and implementation of real-time knowledge-based fuzzy controller system for general purpose industrial applications. In another aspect the invention relates to the development of an intelligent system which implements fuzzy decision-making procedure which employs selected membership function values such that all signal values present at the input to the fuzzy controller contribute to the controller output at all times thereby simulating dynamical system behavior. In yet another aspect, the invention relates to the development of a fuzzy inference engine which implements an approximate reasoning method based on employing elected membership function values of input signals such that the number of rules which the controller fires is reduced. In this way the fuzzy controller becomes fast and requires less memory than other designs of fuzzy controllers.
