Abstract:The traditional model predictive torque control (MPTC) for permanent magnet synchronous motor (PMSM) utilizes the voltage equation in the rotor synchronous rotating coordinate system to predict the values of the next control period. Multiple coordinate rotation transformations with large number of calculations are required. Besides, the current model flux observer is utilized, which is easily affected by the motor parameters. In order to solve these problems, a simplified MPTC is proposed in this paper. The corresponding variable values of the next control period are directly predicted in the static coordinate system, thus the computational burden is significantly reduced. In addition, the proposed strategy is easy to combine with other high-performance stator flux observer techniques to further improve system performance. The experiment verifies the feasibility and effectiveness of the proposed strategy. © 2019 IEEE.
