摘　　要：针对传统的调速系统在控制和实现上存在的缺点,采用直接转矩控制策略和圆形磁链控制方案,对磁链、转矩分别使用2点式3、点式滞环控制,结合TMS320LF2407DSP芯片组建了交流电机DTC变频调速系统,使系统的调速性能得到了提高,更容易实现数字化。并且TMS320LF2407芯片采用定点数运算,使程序执行效率大大提高。Point to the shortage of tradition adjusting system in control and achievement, direct torque control mode is employed to obtain perfect effect, In order to improve the performance of speed adjusting, round flux control is adopted. Moreover, two point and three point mode arc applied in torque hysteresis loop comparators and flux hysteresis loop comparators respectively. Combination with TMS320LF2407DSP, a DTC variable frequency adjustable speed control system is established. Experiment shows that DTC control system performance is improved and is easier to achieve in digital. Fixed data compute is used in TMS320LF2407 to speed up program run.
