摘　　要：为实现异步电动机高性能驱动,提出了矢量控制和直接转矩控制结合的控制策略。该控制策略结合矢量控制和直接转矩控制的优点,将电流矢量控制和电压矢量开关表结合,控制结构相对简单,避免了两种控制方法的一些实现难度。通过仿真模型,并将仿真结果与直接转矩控制系统进行比较分析,结果证实了该控制策略的有效性。A new control strategy was proposed for high performance induction motor drive. This control strategy combined the advantages of vector control and direct torque control and included a current vector control in connection with a switching table. The control structure is relatively simple and the method avoids some implementation difficulties of the two control methods. The model of system based on simulation was developed,according to the new strategy. The simulation resuits under this system comparied with those under the DTC system confirmed the effictiveness of the method.
