A predictive torque control method for permanent magnet synchronous motor without weighting factor

  • Received Date: 2019-06-11
  • The disadvantages of the conventional predictive torque control method for permanent magnet synchronous motor are large calculation amount and the requirement of designing weighting factor, an improved predictive torque control method for permanent magnet synchronous motor without weighting factor was proposed.The method performed predictive control on a stationary coordinate system, avoiding a large number of coordinate transformation operations,thereby simplifying the prediction process.The torque control error and the flux control error were converted into a standard value, and a new objective function was proposed based on the standard value to eliminate the influence of the weighting factor. The simulation results showed that the control effect of the method was better than that of the conventional predictive torque control method,and the system design process was simplified without the coordinate transformation operation and weighting factor design.
