摘　　要：以鼠笼式感应电机为研究对象,在分析电机数学模型的基础上,建立了鼠笼式感应电机的Eulerlagrange方程,结合转子磁链定向原理,将无源性控制应用在感应电机转速控制系统中,并对系统的无源性进行了理论证明。在Matlab的Simulink中建立仿真模型,实现了对电机转速的精确控制。Taking the squirrel-cage induction motor as research object, motor the Euler-lagrange equation of squirrel-cage induction motor is established by analyzing the mathematical model. Combining with the rotor-flux oriented, the passivity-based control method is used in the speed control system of induction motor. Moreover, the passivity of motor control system is verified in theory. The Matlab simulation model is established in Simulink to realize the accurate control of motor speed.
