以新型四相横向磁通永磁电机为研究对象,利用MATLAB/Simulink软件平台以及Simpower System工具箱,对闭环控制系统进行了研究。在传统双闭环调速控制基础上,为滞环电流控制环引入零电平,将滞环分为上滞环和下滞环。综合考虑开关频率与电流THD确定合适的滞环环宽,并根据偏差电流值与滞环环宽比较值得到逆变器控制信号。通过仿真得到各种工况下的电机运行数据,说明该控制方法能够对四相横向磁通永磁电机进行有效控制。

[Abstract]
Based on a new four phase transverse flux permanent magnet motor, the MATLAB/Simulink software platform and Simpower System toolbox were used to study the closed loop control system. Based on the traditional double closed loop speed regulating control, zero level was introduced into the hysteresis current control loop. The hysteresis loop was divided into upper loop and lower loop. The switching frequency and current THD were considered to determine the appropriate hysteresis loop width. The inverter control signal was obtained according to the comparison results of deviation current value and the hysteresis loop width. The running data of motor under various working conditions were obtained by simulation. The simulation results showed that the control method could effectively control the four phase transverse flux permanent magnet motor.
