Fuzzy speed controller of induction machine with 36 sectors DTC based ANFIS hysteresis comparator

In this work, a direct torque control (DTC) with 36 sectors of the induction motor (IM) drive controlled by intelligent regulators is proposed. The proposed command scheme uses the electromagnetic torque errors through an adaptive neuro-fuzzy inference system (ANFIS) and the classic PI speed regulator based the fuzzy logic (FL) regulator. Simulation results by using ANFIS regulator and FL regulator are compared with those of the conventional DTC with 36 sectors. The comparison results of DTC command with intelligent regulators illustrate the reduction in the electromagnetic torque, total harmonic distortion (THD) value of stator current and stator flux ripple and the validity of the proposed control is confirmed by the simulation results.
