In this paper,a dual three-phase synchronous motor vector control system with air-gap field orientation is studied.The mathematical model and the corresponding coordinate transformation of the dual three-phase motor are analyzed.The hybrid model air gap flux observer is derived and the system control scheme is given.The control system can achieve high-precision and high-torque output through the dual three-phase motor vector control.The motor speed and current maintain good output characteristics,and the air gap flux linkage observation accuracy is high.
