摘要：

In this paper, a kind of variable-voltage direct torque control (DTC) method for permanent magnet synchronous motor (PMSM) drive system is proposed. 24 or more voltage vectors with variable voltage on circle traces are obtained. A new switch table is used to select voltage vectors effectively. By theory analysis and simulation research, the proposed control method is proved to enable diminishing the torque ripple, especially in low speed range. In the preliminary experiment, both smooth control of speed and high dynamic performance are achieved.
