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.
