Scalar or vector value generation for fuzzy logic controller - processing measurement valves in two stages using respective fuzzy logic modules and inference devices, and hyper-fuzzification module

摘要

Scalar or vector position values are generated at the output of a fuzzy controller depending on a controller input value e or on several controller input values combined with a vector, e. In the case of a scalar value n, the processing of the process measurement values takes place in two separate stages. The first stage is a fuzzy module (I) with an inference device. At the output of the first stage, it is determined, for all potential values of the output (u) of the fuzzy control, which are favourable. The second stage uses a fuzzy module (II) and an inference device (II). At the output of the second stage, it is determined, for all potential output values, which are unfavourable. The results of the favourable and unfavourable tests are fed to a hyper-inference device. A hyper-fuzzification module calculates the output of the fuzzy controller using the valves obtd. by the hyper-inference device. ADVANTAGE - Precise control.
