摘要
介绍了永磁同步电动机直接转矩控制系统各个环节的MATLAB/Simulink建模方法,并对系统进行仿真,通过转矩和磁链信号的调节使直流信号变换成基本稳定的交流信号,初步实现通过电压和频率变化从而改变速度。
Each part to the PMSM direct torque control system of MATLAN/sim ulink7.1 modeling method is introduced. By system＇s simulation and through torgue and magnetic flux signal adiusting, the dcsignal is transformed into steady ac signal, tha spead change is accomplished by VVVF.
