1SVR440620R1000/ DX021 系統軟件設計 本文研究的永磁空調系統控制軟件全部由LF2407完成，主要是完成空間磁場定向控制，產生SVPWM信號。控制軟件包括初始化程序、主程序和中斷服務子程序三個部分。系統在每次復位后，首先執行初始化程序，完成DSP內部設定和初始狀態的檢測，然后開啟中斷，執行主程序。一旦外部中斷條件滿足時，系統執行中斷服務子程序，直到系統重新復位。圖5為SVPWM中斷服務子程序框圖。
圖5SVPWM中斷子程序流程圖 結論 本文根據永磁同步電動機矢量控制原理和變頻空調器的要求，開發了一套基于DSP的全新變頻空調控制系統。利用LF2407的六個PWM全比較器產生的SVPWM控制信號就可以實現對永磁同步電動機的變頻控制。該空調控制系統充分利用了LF2407的超強實時計算能力和一些集成器件，使整個系統結構簡單、產品開發周期短、可靠性強。
