摘 要:目的分析一般单片机变频调速系统的特点，通过引入专用芯片SA4828改善控制性能。方法通过单片机与SA4828芯片相结合实现对交流异步机的变频调速，给出了硬件电路和软件设计流程。结果系统充分发挥了SA4828的自身特性，分担了部分控制工作，减轻了单片机的任务，单片机可余出机时备作它用，同时系统可靠性增加。结论相对于单纯的单片机控制变频调速系统，引入SA4828的系统控制效果更好。
-Abstract : analysis of the general purpose microcontroller Frequency Control System features By introducing ASIC SA4828 improve performance. By SA4828 chip microcontroller with the combination of AC induction machines VVVF, given the hardware and software design process. Results of the system into full play its characteristics of the SA4828, sharing some control work ease the task of microcontroller, microprocessor can Airport when I prepared for it and at the same time increasing system reliability. Conclusions for the simple microcontroller-control system, the introduction of the SA4828 system control better results.
