摘要
从异步电动机的数学模型出发,推出了在定子坐标系下直接控制定子磁链和转矩的控制规律。利用空间矢量的概念,推导出了直接转矩控制系统中电压空间矢量的选择规则,根据直接转矩控制原理,利用MATLAB软件中的SIMULINK对异步电动机直接转矩控制系统进行了建模和仿真,实验结果表明直接转矩控制具有良好的动静态性能。
On the basis of the mathematical model of asynchronous motor, the control rules for the direct control of stator flux and torque at stator frame is deduced. We achieve a method to choose the proper voltage space vector based on space vector concept. A simulation model of direct torque control for asynchronous motor based on MATLAB/SIMULINK is proposed. The results demonstrate the machine attain well dynamic and static response.
