 Abstract

This study proposes a slip prevention algorithm with a load angle controller to prevent the slip phenomenon in dual-rotor PM synchronous motor (DR-PMSM) drives. A DR-PMSM employs inherent magnetic coupling between the inner and outer rotors for power transmission. This structure may lead to slip and desynchronization between the inner and outer rotors at sudden load variations; therefore, a slip prevention algorithm is necessary to enhance its reliability. Conventional passive slip prevention algorithms may induce load angle oscillation around the critical load angle, which will result in desynchronization between the inner and outer rotors. The PI load angle controller proposed in this study can prevent slip and load angle oscillation near the critical angle. The eff ectiveness of the proposed slip prevention algorithm is verified through mathematical modeling and simulation with MATLAB/Simulink, as well as through an experiment on a horse-power DR-PMSM.
