Development of Methods On-Line Diagnostics of Fuzzy Controller Fuzzification Unit

Control systems based on mathematical apparatus of fuzzy logics are designed to replace an-operator and to be applied in the systems with difficult formalized strategy of control. The main merit of fuzzy controllers (FC) compared to classical variant of control system is their stability to input noises effect. This led to wide spread of control systems based on fuzzy logics including the areas in which production safety and/or human life depend on their productivity. Therefore the problem of FC elaboration possessing self-diagnostics of malfunction in the process of operation is topical. The problems of elaborating the methods of malfunction diagnostics of FC phasification unit on actual time scale (on-line) are considered in the paper, the peculiarities of functioning digital system of fuzzy logical deduction are taken into account.
