- Abstract:
- In view of commutation torque ripple in two sets of parallel winding with difference of 30 electrical degrees in dual-redundancy brushless DC motor,a technique with variable structure and current feed-forward was put forward.Current could be adjusted independently by this strategy,combined with the characteristic of the difference of 30 electrical degrees in the corresponding phase to ensure the stability of commutation torque.In order to increase the response from current,feed-forward control was proposed to improve the current charge rate.The results showed that,compared with traditional method,it could minimize the commutation torque ripple in double-winding permanent brushless DC motor and enhance the stability of the operating system.
