In order to eliminate the weighting value of traditional model predictive torque control (MPTC) of induction motor (IM) and reduce the computational complexity of the algorithm, a deadbeat based MPTC method is proposed. According to the relationship among torque, flux and voltage, an expected voltage vector is obtained based on deadbeat control of flux linkage. By judging the position of expected voltage vector, the number of voltage control sets is reduced from 8 to 2, which reduces the computational burden of MPTC. In addition, the value function contains only one variable of torque to achieve the desired control effect, avoiding the design of weighting value. The simplified three-vector synthesis virtual voltage vector not only expands the vector selection domain, but also reduces the complexity of the traditional virtual voltage vector algorithm and improves the steadystate performance of the control. Simulation and experimental results show that the proposed method has good dynamic and static performance.
