摘要: 針對一般矢量控制系統存在的動、靜態轉矩電流與磁場電流的耦合問題,在分析磁場定向偏差對系統性能影響的基礎上,首次引入自適應逆控制策略的控制方案,并分析了方案的控制特點.理論分析及仿真實驗表明,該控制策略可以有效地解決一般矢量控制系統存在的轉矩與磁場耦合對系統性能造成的影響,提高系統動、靜態性能.

Abstract: Aiming at the coupling problem between dynamic and static magnetic torque and magnetic filed during normal vector control, this paper investigated the influence of the directional deviation of magnetic field on the performance of a normal vector control system. Adaptive inverse control was firstly used to solve this problem, and a novel control scheme was presented. The result of simulation and the theory analysis indicate that the proposed scheme can solve the influence of coupling between magnetic torque and magnetic filed in the system with normal vector control, and can effectively improve the dynamic and static performance.
