Adaptive inverse control of an exchange frequency conversion vector control system

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.
