Abstract:

Since dual three-phase permanent magnet synchronous motor (DTP-PMSM) has strong electromagnetic coupling in natural coordinate system with complex control model, a vector control algorithm of the DTP-PMSM was explored and a model of the DTP-PMSM was established based both on a space vector decoupling theory and on a double-dq transform theory to analyze the relationship and the difference of the two algorithms. A control model was built on a simulation platform of the motor with realizing a constant speed control for the two vector control algorithms. The differences of control performance between the two vector-control-algorithms were compared through analyzing simulate results. The results show that the spacevector decoupling-control and the dual-dq transform control are highly consistent in theory. The space-vector decoupling control algorithm can achieve a better energy decoupling-control relative to the dual-dq transform control algorithm.
