A new self tuning fuzzy controller design and experiments

A fuzzy logic controller design with self-tuning features for both the database and the rule base is proposed. The original rule base and the database of the controller are based on the designer's experience, which may be heuristic and subjective. Real-time implementation of the controller using an experimental setup shows that the design performs very well for a complex nonlinear system. The example case considered is a DC-motor-drive four-bar linkage system, which is a representative transmission used in several machines. Real-time control was implemented using the C language. The hardware configuration is described.<>
