【摘要】 在直接力短控制系统中，异步电机定子电阻值在运行过程中一直是变化的，严重影响了系统的低速性能。本文就这一问题进行了讨论，并设计了定子电阻在线模糊（Fuzzy）观测器，从而为改善系统的低速性能找到了一条途径。更多还原

【Abstract】 In the DTC system.the stator resistance of asynchronous motor has been constantly changing in the operation,which affects the performance in low speed of the system. In this paper,the authors discuss the problem and design a Fuzzy On-line observer for the stator resistance. So a way is discovered to improve the performance in low speed of system.更多还原
