A direct torque control (DTC) method for dual three phase induction motors using a fuzzy inference system

In this work a fuzzy inference system is employed for the control of a PWM based direct torque control (DTC), driving a dual three phase induction machine (DTPIM). DTPIM has two, three phase windings spatially phase shifted by gamma (=60deg in this research) electrical degrees. The proposed control scheme uses a Fuzzy inference system to modulate the phase of stator voltage vector applied to the DTPIM. The simulation results show that the system performances are satisfactory using the proposed method.
