摘要:
针对两套并联绕组互差30°电角度的双余度无刷直流电机换相转矩脉动问题展开研究.提出一种基于变结构电流前馈的转矩控制方法.该方法结合对应相绕组轴线互差30°的特点,在均流控制的前提下,使用变结构控制策略独立控制两套绕组的电流以保证电机在换相时刻输出稳定的转矩.为了增加电流的响应速度,采用电流前馈控制方法提高电流的变化率.在MATLAB/ Simulink环境下搭建模型进行仿真.结果表明,与传统的双余度电机均流控制策略相比,基于变结构电流前馈的转矩控制策略能够有效地降低电机的换相转矩脉动.
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.
