摘 要:在速度分區(qū)控制的基礎(chǔ)上提出一種混合勵磁電機矢量控制算法,該方法綜合考慮了負載轉(zhuǎn)矩、勵磁電流及母線電壓對弱磁基速的影響,在線動態(tài)計算弱磁基速。在弱磁區(qū),保持氣隙合成反電勢恒定,利用勵磁電流和d 軸電流共同弱磁升速。采用Matlab/Simulink仿真軟件建立混合勵磁同步電機控制系統(tǒng),對所提算法進行驗證。仿真結(jié)果表明該算法可實現(xiàn)混合勵磁電機低速大轉(zhuǎn)矩和高速寬調(diào)速范圍運行。

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
