Abstract :
This paper proposes the practical implementation of a fuzzy logic control scheme applied to a two phase (d-q) current model of an induction motor. Most conventional fuzzy controllers use fuzzy logic to tune a PI or PID. The fuzzy logic control scheme does not depend on the conventional PI or PID model. It directly transforms the inputs, speed errors and rate of change in speed errors, into the output quantity, the change in inverter command frequency. The proposed approach is simpler in implementation and its trajectory tracking capability was investigated. The experimental results show that it has a superior performance compared to a fuzzy tuned PI controller or a simple PID controller
