| 摘 要： | 针对无刷双馈电机直接转矩控制系统中参数变化引起的电机特性不稳定的问题,在电压-电流-磁链模型的基础上,提出了一种基于模型参考自适应的定子磁链辩识方法。考虑定子电阻的影响,准确估算磁链和转矩,并将其应用在无刷双馈电机直接转矩控制系统中。仿真结果表明:该方法有效地减少了无刷双馈电机定子电阻变化对系统特性的影响,提高了系统的稳定性,而且该系统对负载的变化具有很强的鲁棒性。

| Abstract: | Due to the variation of brushless doubly-fed machines parameters with time in a direct torque control system,on the basis of the voltage and current flux model,a method for identifying stator flux on model reference adaptive is proposed,considering the impact of stator resistance,the flux and torque is computed accurately,and is introduced into a direct torque control system.The results of simulation show that this method can effectively reduce the influence of variation of stator resistance on machines performance and has robust performance for the variation of load. |
