基于TMS320F28035芯片為控制核心的空間矢量異步電機變頻器 我們設計的異步電機變頻調速器以TMS320F28035芯片為控制核心,通過輸出三相PWM波控制智能功率模塊IPM驅動三相異步電機。我們使用空間矢量SVPWM算法,并對其進行了優化。采用檢測反電勢的方法省去了昂貴的光電編碼器,大大節省了成本。同時開創性的研發了自動根據運行環境調節的自適應變頻算法,使我們的變頻調速器可以在電網條件惡劣的鄉村山區工作,由此該變頻器已被一家民用水泵生產企業預訂。關鍵字 變頻器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.

反向傳播(back-propagation,BP)算法是一種計算單個權值變化引起網絡性能變化值的較為簡單的方法。由于BP算法過程包含從輸出節點開始,反向地向第一隱含層(即最接近輸入層的隱含層)傳播由總誤差引起的權值修正,所以稱為"反向傳播"。
