Abstract:
In order to reduce the larger torque and flux ripples of the traditional direct torque control,and obtain the constant inverter switching frequency,an improved direct torque control method of PMSM based on reference flux vector calculation was studied. The principle and structure of the direct torque control with reference flux vector calculation was discussed in-depth by analyzing the control effect of the change of the stator flux vector on the torque and flux. Then the torque loop control model was obtained by partly linearizing the torque equation,and the parameter of the torque loop controller was designed after analyzing the error of the linearization procedure. Finally,the feasibility and validity of the studied control method was verified by the simulation and experiment results.
