Based on the expressions of flux and torque of surface permanent magnet synchronous motor (SPMSM) direct torque control (DTC) system with the angle of applying voltage vector as the variable, the values of stator flux and torque at the next sampling point after applying voltage vector with different angle were given. The objective function of flux error and torque error was proposed. The predictive control would select the optimal angle which minimized the objective function. Simulation results showed that the SPMSM DTC system under the control of proposed strategy worked properly. Control performances of SPMSM DTC system were given using different partitioning methods of voltage vector selection area. Considering control performance and calculation burden, quartering the voltage vector selection area was an ideal way.
