摘要 文章基于MRAS的感应电机全阶观测器数学模型,介绍了一种利用观测器误差信号同时估计感应电机转子转速和时间常数的算法,分析了该算法在李雅普诺夫意义下的稳定性。仿真结果表明该算法是有效和稳定的。 Based on the full order observer of induction motor, this paper presents a method using the error between real model and observed model to simultaneously estimate the rotor speed and time constant,and analyse the stability of the arithmetic under the meaning of Lyapunov. Finally, the simulation result shows that the arithmetic is efficient.
