摘要
针对异步电机交流调速系统的特点,采用了直接转矩控制(DTC)交流变频调速方案,直接对电机定子磁链和电磁转矩进行控制,避免了矢量控制中复杂的变换和参数运算,使控制结构简单。应用Matlab/Simulink对直接转矩控制的定子磁链近似圆形控制的方法进行了仿真和分析,验证了系统的正确性。
For the characteristics of asynchronous motor control system, the program adopts direct torque control (DTC) and AC frequency converter to control directly the motor stator flux and torque, to avoid the complicated transform and parameters calculation in vectors control, to make the structure of control simple. The accuracy of the system is verified by the simulation and analysis on the direct torque to control stator flux by the control method of quasi-circular based on MATLAN/Simulink.
