Analysis and Speed Ripple Mitigation of a Space Vector Pulse Width Modulation-Based Permanent Magnet Synchronous Motor with a Particle Swarm Optimization Algorithm
A method is proposed for reducing speed ripple of permanent magnet synchronous motors (PMSMs) controlled by space vector pulse width modulation (SVPWM).A flux graph and mathematics are used to analyze the speed ripple characteristics of the PMSM.Analysis indicates that the A Transformer-Based Approach for Efficient Geometric Feature Extraction from
