This paper presents a fully digital direct torque control (DTC) scheme for a five-phase induction motor based on a 32-bit floating-point TMS320C32 Digital Signal Processor (DSP). The similarities and differences of DTC of the five-phase and three-phase induction motors are analyzed and investigated. In the case of the five-phase induction motor, DTC method has unique advantages. Compared with 8 voltage vectors of the three-phase induction motor drive system, DTC of the five-phase motor drive system has 32 space voltage vectors with different magnitudes. The increased number of the space voltage vectors enables DTC of the five-phase induction motor greater flexibility in selecting the inverter switching states, and achieves a better control of the stator flux and torque. Simulation and experimental results validate the theoretical analysis, and further demonstrate that DTC of the five-phase induction motor yields better performance than that of the three-phase induction motor.
