通过设计异步电动机的变频调速系统，其主电路采用交-直-交型电路形式，控制方式采用恒压频比（U／F）控制策略，根据系统参数对电路器件进行参数计算和选型，采用智能功率模块（IPM）作为逆变电路功率开关器件，同时以TI公司的DSP（TMS320LF2407A）作为控制核心来提高系统的精度和稳定性。实验及仿真结果表明该驱动系统工作性能稳定、抗干扰性强，具有很高的应用价值。

By designing motor variable frequency control system, AC-DC-AC-circuit form is used in its main circuit and U/F control strategy is used in its controlling method. Based on the system parameters, the calculation and se-lection of the component parameters are carried out. Finally, the intelligent power module (IPM) is used as a power inverter circuit switching devices, and TI DSP (TMS320LF2407A) as a core control to improve the precision and stability. The experimental results indicate that the driving system has the stable performance high anti-interference and high value.
