摘　　要：介绍了一种基于模型参考自适应(MRAS)的感应电机转子时间常数实时辨识方法。根据MRAS系统中参考模型和可调模型的状态误差调节可调模型的参数,在线辨识转子时间常数。理论分析证明该算法具有李雅普诺意义下的全局稳定性。最后对该算法进行了仿真验证。A real-time estimation scheme for the rotor time-constant of induction motor based on MRAS is proposed. According to error between the state variables of the reference model and the adjustable model,we can on-line tuning the Tr to Tr.The theory analysis prove the arithmetic has global stabilization under the means of LIYAPNOV .Finally ,the simulation result is presented.
