A new FOC technique based on predictive current control for PMSM drive

This paper presents a new predictive current control (PCC) strategy using field oriented controller (FOC) for permanent magnet synchronous motor (PMSM). The suggested technique estimates the desirable electrical torque to track mechanical torque at a fixed speed operation of PMSM. The estimated torque is used to calculate the required current of motor based on conventional FOC technique. Finally, the duty cycle of the inverter is determined to feed the PMSM at a fixed switching frequency. The performance of the control schemes is evaluated in terms of torque and current ripple, and transient response to step variations of the torque command. Numerical simulations tests have been carried out to validate the proposed method in MATLAB.
