Slotless surface-mounted permanent magnet synchronous machines with high pole numbers generally have relatively low inductance, which will lead to significant current harmonics under PWM-driven inverters. Current harmonics can cause additional losses and torque ripples, severely impacting temperature rises and mechanical vibrations. Accurate prediction of current harmonics is crucial for machine performance calculation and drive system design. This paper proposes a frequencydomain analytical method to predict the current harmonics with high fidelity equivalent circuit models. The harmonic prediction method is validated experimentally under a wide range of operating conditions and improves the prediction accuracy by up to 75% compared to the existing analytical modeling methods. The prediction error using the proposed method is generally maintained below 10%, making it an effective tool for practical applications.

“…The advantage of this method is its simplicity and fast solving speed, but it does not consider motor saturation effects and additional losses, leading to large prediction errors. In [22], flux-linkage lookup tables with saturation information were used to replace the constant L parameter to improve accuracy.…”

The main contribution of this review work is to show how various control techniques are used to manage the speed of Permanent Magnet Synchronous Motor (PMSM). The PMSM’s are mostly used in electric vehicles, electric traction and high performance industrial drive applications. In this article conventional sensorless techniques are compared with machine learning techniques such as fuzzy logic, artificial neural network and neuro-fuzzy controllers to control the speed of PMSM drive based on vector control approach. The benefits of machine learning techniques used in sensorless PMSM drive are easy to design, less execution time and fast access speed control. The various controlling techniques used in controller along with its complexity, advantages and drawbacks are discussed in this article. The above mentioned controlling techniques are implemented and simulated by using MATLAB R2019b/Simulink software based on sensorless Model Reference Adaptive System (MRAS) with the help of Field Oriented Control (FOC) strategy of PMSM drive. By comparing the all sensorless controlling techniques in simulation study, it is identified that the combination of neuro-fuzzy controller gives the best speed control performance than other controllers.
