Using assemble language to realize the conventional DTC system based on TMS320LF2407. The experiment results shows that the torque response is fast but the torque and flux ripples are large at the low speed.

• 基于TMS320LF2407采用汇编语言编程实现传统直接转矩控制系统,程序包括AD采样、磁链转矩计算、滞环比较、磁链区间判断以及PWM输出等。 实验结果验证了传统直接转矩控制系统转矩响应速度快,但低速时磁链和转矩脉动较大。
