摘　　要：针对一般矢量控制系统存在的动、静态转矩电流与磁场电流的耦合问题,在分析磁场定向偏差对系统性能影响的基础上,首次引入自适应逆控制策略的控制方案,并分析了方案的控制特点.理论分析及仿真实验表明,该控制策略可以有效地解决一般矢量控制系统存在的转矩与磁场耦合对系统性能造成的影响,提高系统动、静态性能.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.
