基于DSP的斩波内反馈串级调速系统的研究

Research of cascade speed regulating system of inner-feeding motor based on DSP chopping control

为了完善国内风机和泵类等负载的调速系统,在串级调速系统的基础上,提出了一种带斩波模块的内反馈串级调速系统;指出了斩波式内反馈串级调速系统的优点;介绍了当前比较流行的用于调速系统控制的数字信号处理器(DSP)TMS320F28335。实验结果表明,采用斩波式内反馈串级调速系统控制的风机比采用传统串级调速系统控制的风机更能节约电能。该斩波式内反馈串级调速系统已广泛地应用于工业生产中。

Aiming at improving the domestic cascade speed regulating system such as fan and pump and so on, an inner-feeding cascade speed drive system with chopper which based on the cascade speed drive system was discussed, the excellence of the inner-feeding cascade speed drive system with chopper and the digital signal processor（DSP） TMS320F28335 which was widely used in the speed regulating system were introduced. The experiment results show that the inner-feeding cascade speed drive system with chopper is better than traditional cascade speed drive system in making fan save electric power. The inner-feeding cascade speed drive system with chopper has been widely used in the industry.
