In this paper, direct torque control (DTC) of fivephase
induction motor is developed. A novel DTC scheme is
proposed, where fast torque response with low ripple in the
stator flux and torque of five-phase induction motor can be
achieved. In comparison with DTC for three phase induction
motor, the five-phase DTC system has thirty-two space voltage
vectors, which provide greater flexibility in selecting the inverter
switching states thus accomplishing a more precise control of the
stator flux and torque. Simulation and experimental results
clearly demonstrate a better dynamic and steady state
performance with DTC for five-phase induction motor, which
suggest that the combination of DTC with multi-phase induction
motor have a great practical prospect in motor drives.
