Design and Simulation of Fuzzy Direct Torque Control System

This paper proposes a novel structure of fuzzy stator direct torque control for induction motor with fuzzy stator resistance estimator. Fuzzy logic is used for estimating the stator resistance and choosing the switching state, which can improve the performance at low speeds and the response of the system. Also the paper uses MATLAB/SIMULINK to build the simulating model of the system. Some simulating result is presented to demonstrate this model is true, and the method has the advantage to study in the engineer.
