-This paper investigates the feasibility of a sensorless field oriented control (FOC) combined with a finite control set model predictive current control (FCS-MPC) for an interior permanent magnet synchronous motor (IPMSM). The use of a FCS-MPC makes the implementation of most of the existing sensorless techniques difficult due to the lack of a modulator. The proposed sensorless algorithm exploits the saliency of the motor and the intrinsic higher current ripple of the FCS-MPC to extract position and speed information using a model-based approach. This method does not require the injection of additional voltage vectors or the periodic interruption of the control algorithm and consequently it has no impact on the performance of the current control. The proposed algorithm has been tested in simulation and validated on an experimental setup, showing promising results.

“…Although this control type's use has majorly focused on converter control, the trend of its application for variable speed drives control is also on the rise [8][9][10][11][12][13][14][15][16][17][18].…”

“…In the area of motor drives, MPC has been very successfully employed for predictive torque control (PTC) [9,10,13,14] and predictive current control (PCC) [13], and predictive flux control (PFC) [11] and speed control [15] of induction motor drives. The research extended the use of MPC to sensorless [14,16,17] as well as fault tolerant [12] induction motor drives.…”

-The paper presents a new implementation of direct flux and current vector control of an induction motor drive using the techniques of model predictive control. The advantages offered by predictive control are used to enhance the dynamics of direct flux vector control. To minimize the problems of variable switching frequency inherent to finite control set predictive control, an alternative approach using pulse width modulation is studied for command execution as occurs in the so-called modulated model predictive control. A comparison between finite control set and modulated model predictive control is presented and the results are also compared with the control implementation through traditional proportional-integral regulators to highlight the advantages and drawbacks of predictive control based strategies. Apart from a greater harmonic content in stator currents, the predictive control can offers control dynamics comparable with proportional-integral control while maintaining immunity against machine parameter variations and excluding the need for controller tuning.

“…The deadbeat control in combination with the space vector modulation (SVM) technique is able to provide the lowest distortion and the lowest current ripples [4]. In the attempt of pushing the system dynamic performance without increasing the converter switching frequency and/or using expensive new Wide Band Gap (WBG) devices, another emerging model based control technique, Finite Control Set Model Predictive Control (FCS-MPC) [5][6][7][8], has received in recent years a great interest from the academic community. It uses the model of the system to predict its future states for every possible control action.…”

Abstract-This paper presents a novel deadbeat current control approach for Permanent Magnet Synchronous Motors (PMSMs) drives capable of operating at a controller sampling frequency multiple of the power converter switching frequency. The proposed technique permits to achieve a constant switching frequency and an optimal current ripple along with a high current loop bandwidth and robust behaviour to parameter variation.
