一種開關磁阻電機的專用集成電路研究與開發(fā)

為了提高高速開關磁阻電機（SRM）控制器的系統(tǒng)性能，簡化控制電路，計了一種具有
角度控制功能的專用集成電路（ASIC）SR3P10k07A。本文開發(fā)了一套基于ASIC高速SRM數(shù)字控制器。角度解算等功能由SR3P10k07A完成，執(zhí)行效率高、抗干擾能力強。而微處理器（MCU）僅負責控制算法實現(xiàn)和狀態(tài)檢測等功能，對MCU的資源需求大幅減少，因此可選用單片機來實現(xiàn)高速SRM的實時控制。最后，該控制器在一臺高速SRM樣機上進行了實驗，樣機最高轉(zhuǎn)速達到130,000r/min。試驗結果表明,所設計的專用集成電路可有效滿足高速SRM的控制要求。
Abstract： An application Specific Integrated Circuit (ASIC) named SR3P10K07A was designed to improve the system performance and simplify the control circuit of the high speed Switched Reluctance Motor (SRM) in this paper., which owns proper hardware functions such as the angular position control and so on Based on ASIC, a digital controller of high speed SRM was developed. In this controller, some functions can be accomplished by ASIC with high efficiency and strong anti-interference capability, such as rotor position signals processing and control angles calculation. At the same time, the Micro Control Unit (MCU) will be responsible only for the realization of control algorithm and state detection. Therefore, the system can significantly reduce the needs for the resource of MCU, and the Single Chip Microcomputer (SCM) can be used to achieve the real-time control of high speed SRM. Finally, the controller was used in an experiment for the high speed SRM, and the maximum speed of SRM can reach 130,000r/min. Consequently, the results show that it can meet the controlling requirement of high speed SRM effectively.
