Abstract：In this paper, a fast predictive direct torque control (PDTC) based on weighting factor elimination and finite control set optimization is presented. The weighing factors are removed and the number of elements in finite control set are reduced. The heavy computing burden of conventional PDTC for dual three-phase permanent magnet fault tolerant machine system are also released. Firstly, according to the deadbeat direct torque and flux control, the variables with different dimensions in the cost function are all equivalent to the voltage vectors, eliminating the weighting factor of stator flux. Then, based on the large flux leakage of permanent magnet fault tolerant machine, only the voltage vectors or virtual voltage vectors whose zero-sequence voltages are zero are selected as the elements of finite control set. As a result, the weighting factor of zero sequence is eliminated, and the elements number of finite control set is decreased from 64 to 19. Besides that, the zero-sequence currents are improved. Finally, a fast method which just needs one time to select the optimal voltage vector is designed. The experimental results verify the feasibility and effectiveness of proposed PDTC.
