    This paper reviews current methods of integrating genetic algorithms with fuzzy logic control. A fuzzy logic controlled genetic algorithm (FLC-GA) is proposed where operator selection and parameter adjustment is carried out dynamically and automatically. The fuzzy logic controller facilitates this automated control by employing an associated rule base and inference engine. This decides, using feed... View full abstract»

An incremental optical encoder is used as the position transducer, allowing the achievement of a minor loop. The numerical control algorithm is implemented using an IBM PC together with a specialized interface for stepper motors. The solution was obtained in two steps: the first was a nonlinear control law an... View full abstract»
