摘 要:在速度分區(qū)控制的基礎(chǔ)上提出一種混合勵(lì)磁電機(jī)矢量控制算法,該方法綜合考慮了負(fù)載轉(zhuǎn)矩、勵(lì)磁電流及母線電壓對(duì)弱磁基速的影響,在線動(dòng)態(tài)計(jì)算弱磁基速。在弱磁區(qū),保持氣隙合成反電勢(shì)恒定,利用勵(lì)磁電流和d 軸電流共同弱磁升速。采用Matlab/Simulink仿真軟件建立混合勵(lì)磁同步電機(jī)控制系統(tǒng),對(duì)所提算法進(jìn)行驗(yàn)證。仿真結(jié)果表明該算法可實(shí)現(xiàn)混合勵(lì)磁電機(jī)低速大轉(zhuǎn)矩和高速寬調(diào)速范圍運(yùn)行。

Abstract: Based on speed stage control, this paper proposed a kind of vector control algorithm for hybrid excitation synchronous machine (HESM). In this method, load torque, excitation current and DC bus voltage were considered when the fux-weakening base speed was calculated. The air gap synthesis back-electromotive force was kept constant in high-speed region applying excitation and d-axis current for fux-weakening. Simulink in Matlab was adopted to build the HESM control system and the algorithm was validated. The simulation results show that this new control system has higher output torque and broader constant power operation scope.
          Key words: hybrid excitation synchronous motor; stage control; flux-weakening base speed; synthesis back-electromotive force
