چکیده:

This paper presents a new predictive current control (PCC) strategy using field oriented controller (FOC) for permanent magnet synchronous motor (PMSM). The suggestedtechnique 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. In order to increase the FOC-PCC torque response, a proportional gain controller is added to the proposed system. The proportional gain value is tuned to have a regulated torque and flux response. The performance of the controller is evaluated in terms of torque and current ripple, andtransient response to step variations of the torque command. In addition, the relation between proportional controller and rotor inertia system is evaluated. Numerical simulations tests have been carried out to validate the proposed method in MATLAB.
