An Intelligent System for Manufacturing Fibre Optic Components
This paper presents an intelligent system for assembling optical fibre components. The system aligns the core of a fibre relative to a laser emitter to maximise the light output from the fibre. It searches for the location yielding the maximum light output by applying a gradient-based algorithm enhanced with momentum information. The parameters of the algorithm are adjusted on-line by a fuzzy controller according to the progress of the alignment operation. The control knowledge base is automatically generated using a new evolutionary algorithm. The fuzzy logic controller demonstrated a robust performance with alignment times and accuracies comparing favourably against those obtained using a manually designed controller.
thanks for your question. at the moment, rule base simplification is done manually. referring to the tables of fig. 5, the system output is the same from input condition I13 to input condition I16 (the rightmost area). the last four terms of linguistic variable I1 can therefore be collapsed into one, let's call it I13', covering the range formerly covered by terms I13, ..., I16. we will then get a more compact 4x4 RB matrix.

Could you please explain briefly, how ’Rule base simplification' works? I'm referring Fig. 5. Thanks.
