PERMANENT MAGNET SYNCHRONOUS MOTOR TORQUE RIPPLE REDUCTION USING PREDICTIVE TORQUE CONTROL.

The control a permanent magnet synchronous motors is the subject of this study and the torque ripple reduction in these motors is the main goal of this work. Torque and flux are controlled using a predictive model and vector control. Because it is commonly employed in regulating electric motors. Space vector control and predictive torque control are two permanent magnet synchronous motor control approaches used in this study. Predictive control was determined to be more effective in terms of response and action after a Mat lab simulation of the two approaches. Predictive torque control covers all potential switching states that decrease actual torque and flux ripples as well as total harmonic distortion. The benefits of predictive torque control include simple principles, an easy-to-use console, and the ability to implement limits quickly. However, there are some drawbacks to this technique, including the requirement for bigger accounts and faster machines. The fundamental principles of the control techniques discussed are provided. A permanent magnet synchronous motor powered by a two-level power converter is then used to simulate the control approaches. Their performance in comparison is based on the obtained results. An analytical model of the predictive torque control is presented utilizing SIMULINK to explain the operation. [ABSTRACT FROM AUTHOR]
