| 摘 要： | 基于非线性控制系统的绝对稳定性定理，提出了一种新的通用异步电机转速自适应辨识方法。通过理论分析可以证明传统的MRAS（模型参考自适应方法）转速辨识算法就是该理论的一种较优实现形式，从而从另一方面证明了MRAS转速辨识方法的稳定性，并且解决了传统MRAS算法中武断的忽略磁链观测误差的问题。在MATLAB／Simulink环境下对该理论进行了仿真验证。

| Abstract: | A new general arithmetic to design speed estimation arithmetic of asynchronous motor based on the absolutely stability theorem of nonlinear system is introduced. The well-known MRAS based speed estimation arithmetic is proved to be an oriental implement of it, the problem that the error between observed rotator flux and its real value is difficult to be obtained is also be solved by this method. The validate of the theory is checked in simulation. |
