本文以極具發展前景的pmsm交流伺服驅動系統為研究對象，在綜合分析現代交流伺服系統發展趨勢和借鑒前人研究成果的基礎上，針對發展高性能pmsm交流伺服驅動系統的需要並結合控制理論和軟開關技術的新發展，在理論研究的基礎上，設計實現了一套完整的基於軟開關技術並應用dsp （ tms320f2812 ）和cpld （ epf10k10lc84 - 15 ）為控制核心的全數字化pmsm交流伺服驅動系統。 -
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，從而有效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，來自位置傳感器的三相位置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、電流雙閉環控制策略，力求構建高性能的稀土永磁無刷直流電動機全數字實時控制系統。
