Abstract
We introduced the mathematical model of permanent magnet synchronous motors(PMSM) according to the principle of the full flux linkage of motors and the rotor flux intersected by the stator flux being equal as well as the theory of constant flux linkage control.Through the mathematical equation of electromagnetic torque and the stator current of permanent magnet synchronous motors,the relationship between the current and the torque was established by the fitting method of table lookup.The motor model was estcablished by using MATLAB software simulation.The constant flux linkage control was compared with the control of id =0 and maximum torque per ampere.The simulation results indicated that under constant flux linkage control,the steady-state error was 0.478%,the adjusting time was 7.7% and 27.6% faster than the first two kinds of control.Meanwhile,the power factor of constant flux linkage control was 0.72,which was also greater than that of the first two kinds of control(0.72 and 0.62) respectively.关键词
