摘要：
The torque ripple of switched reluctance motor can be effectively suppressed by direct torque control technique. The serious nonlinearity is caused by the doubly salient structure and the severe saturation of the magnetic circuit of the switched reluctance motor, and thus the fixed parameters can't adapt to the change of the working conditions and the torque ripple is relatively large. To solve this problem, a method based on fuzzy PI is proposed to improve the dynamic response of the switched reluctance motor and restrain torque ripple. By establishing the nonlinear model of switched reluctance motor and using the finite element simulation software, the flux linkage of motor, the static characteristics of inductance and torque were calculated. The simulation and experiment results show that the system has good dynamic and static performance. It can improve torque run away phenomenon and reduce the torque ripple effectively. The stability of the control system is also improved. © 2019, Harbin University of Science and Technology Publication. All right reserved.
