  In the drive control of permanent magnet synchronous motors (PMSMs), the control system must be designed to work in different conditions and against of changes in motor parameters and unknown disturbances. In order to enhance the drive performance of PMSM motor, the model-predictive control independent of current and speed model (MFPCSC) is proposed in this article. This method only uses the input and output of the system and does not involve the motor parameters in the drive control, and it is robust to the changes of the motor parameters. The conventional model-independent predictive control method requires setting several control parameters. To improve the performance of the drive system of this motor and make it robust to changes in parameters and disturbances, the proposed MFPCSC method is designed based on the nonlinear disturbance observer (NDO). This observer can estimate system disturbances with more accuracy and stability, and the amount of calculations is small. The simulation and practical test results of the proposed MFPCSC method combined with the NDO show that the proposed control method has high robustness to parameter changes, favorable transient response, small output ripple, and improved transient characteristics, and can accurately and stably estimate system disturbances.
