  1. To modify the fp control word, then the run - time startup code will set the x87 fpu control word precision - control field to 53 - bits, so all float and double operations within an expression will occur with 53 - bit significand and 15 - bit exponent

    修改fp控制,則運行庫啟動代碼會將x87 fpu控制精度控制欄為53,這樣,表達式內的所浮點運算和精度運算都以53數和15指數進行。
  2. Effective double - word location

  3. In the design of real - time control system, the paper takes three - phase full - bridge mosfet inverter as the real - time control main circuit, and adopts a control scheme with 120 ? switching mode combined with half - bridge pulse width modulation ( pwm ), which would avoid straightthrough short of a certain bridge. phase current is detected by single current sensor ; three - phase position signals generated by position sensors could not only supply commutation information for inverter, but also be used for speed detecting based on signals " period measurement, which makes the speed sensor unnecessary. the whole control system adopts speed and current dual closed - loop control strategy in order to construct a high performance rare - earth permanent magnetic brushless dc motor ( repm bldcm ) full - digital real - time control system

    在實時控制系統的設計中,本文以三相全橋mosfet逆變電路作為實時控制主電路,採用120導通方式結合半橋pwm調制的控制方案,從而地避免了橋臂的直通短路;本文用單電流傳感器實現對相電流的檢測,來自傳感器的三相信號不僅為逆變電路提供換相信息,而且也用於基於信號周期測量的轉速檢測,這樣就省去了速度傳感器;系統採用的是速度、電流閉環控制策略,力求構建高性能的稀土永磁無刷直流電動機全數實時控制系統。
