| 摘 要： | 本文提出了一种将直接转矩控制（DTG）与定子磁场定向控制（SFOC）相结合的电压调节方式，一方面采用定子磁场定向控制，将交流量转化成直流流量以便于调节，另一方面又采用直接转矩控制技术调节转矩和磁通的偏差以加快响应，同时使用电压调节法避免了电流的解耦，而转矩和磁通的连续调节方式则克服了传统的直接转矩控制带来的转矩脉动。并通过仿真证明了该调速系统的性能。

| Abstract: | A new voltage adjust mean with Direct Torque Control (DTC) and Stator Flux Oriented Control (SFOC) combined is presented in this paper. First, by using FOC in the system, AC parameters can be converted in DC for convenient control. On the other hand,by using DTC the transient performance of the system can be improved. At the same time, by using the method of voltage control, current decoupling can be avoided by controlling the flux and torque continuously, and the torque ripple can be reduced. The effect of proposed method has been proven by simulation. |
