摘　　要：介绍了ALA转子电机的基本原理及其直接转矩控制(DTC)的基本理论。在Simulink环境下,搭建ALA转子电机及其直接转矩控制系统的模型。对ALA转子电机DTC系统起动及负载变化等情况进行了研究。仿真结果表明,直接转矩控制可以克服ALA转子电机开环难以起动的缺点。ALA转子电机的直接转矩控制仿真系统结构简单,实现容易,动态响应快,对ALA转子电机的实用化有相当大的意义。The principle of Axially-Laminated Anisotropic（ALA） Rotor Motor and the theory of its direct torque control（DTC） are introduced. The simulation model of DTC of ALA rotor motor is established based on Matlab/Simulink. The dynamic response of no-load starting and step-load of ALA rotor motor are researched. The result of simulation indicates that the DTC of ALA rotor motor can overcome the disadvantage of the badiy starting in open-loop system. The simulation system of DTC of ALA rotor motor is significative in the practive reseach of ALA rtor motor, which has advantages of simple struct, easy realized and fast dynamaic response.
