  1. 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mosfet逆變路作為實時控制主路,採用120導通方式結合半pwm調制的控制方案,從而有效地避免了通短路;本文用傳感器實現對相的檢測,來自位置傳感器的三相位置信號不僅為逆變路提供換相信息,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、雙閉環控制策略,力求構建高性能的稀土永磁無刷動機全數字實時控制系統。
